    Appeal from the United States District Court

    A RGUED S EPTEMBER 20, 2012—D ECIDED JANUARY 23, 2013
    Before E ASTERBROOK, Chief Judge, and M ANION and
    T INDER, Circuit Judges.
    T INDER, Circuit Judge. In August 2010, Jeffery Dickerson
    sold several bags of crack cocaine to Debra Vankuiken
    in exchange for five guns. Based on that trade, a jury
    convicted Dickerson of knowingly possessing firearms
    in furtherance of drug distribution under 18 U.S.C.
    § 924(c). Dickerson appeals, contending that 18 U.S.C.
    § 924(c) does not cover such guns-for-drugs exchanges;
    2                                               No. 11-3285
    that the district court’s jury instructions stating otherwise
    were given in error; and that a discrepancy between the
    offense date charged in the indictment and the date
    for which the government offered evidence at trial war-
    rants reversal. For the reasons set forth below, we affirm.
    I. Background
    A. The Drugs-for-Guns Exchange
    From 2008 until his arrest in September 2010, Dickerson
    regularly sold crack cocaine to Vankuiken in Kankakee,
    Illinois. In August 2010, Vankuiken approached Dicker-
    son to make a purchase, but was short on cash. Dickerson
    proposed a trade: if Vankuiken could obtain guns, Dicker-
    son would be willing to give her crack cocaine in exchange.
    Later that month, Vankuiken took five stolen guns,
    which were unloaded, to Dickerson’s Kankakee apart-
    ment. Dickerson agreed to accept the guns as payment
    for crack cocaine. Dickerson and Vankuiken then drove to
    a storage facility, where Dickerson left the guns in a
    rental unit. Finally, the two returned to Dickerson’s
    apartment, where Dickerson gave Vankuiken several
    bags of crack cocaine to complete the trade.
    On September 24, 2010, law enforcement officers with
    the Kankakee County Major Crimes Task Force arrested
    Vankuiken on suspicion of stealing the five guns. She
    agreed to cooperate with the officers, and directed them
    to Dickerson’s storage unit, where they found a cache
    of weapons and accessories, including three machine-
    guns and two handguns. The officers then arranged for
    No. 11-3285                                                3
    Vankuiken to make a controlled purchase of crack
    cocaine from Dickerson. Under the officers’ supervision,
    Vankuiken purchased $50 worth of crack.
    On September 25, Task Force officers lawfully searched
    Dickerson’s Kankakee apartment, where they recovered
    25.6 grams of crack cocaine. That same day, officers
    executed a search warrant on a second Dickerson apart-
    ment, in the nearby town of Bourbonnais, Illinois.
    The officers recovered 100 grams of crack cocaine and
    a loaded Smith & Wesson revolver, located approxi-
    mately three feet away from the drugs, at this second
    apartment.
    B. The Indictment & Trial
    A federal grand jury indicted Dickerson for three drug-
    and firearm-related offenses. In February 2011, the
    grand jury filed a Superseding Indictment containing a
    revised version of these three charges. Count 2 of the
    Superseding Indictment contains the charge at issue in
    this appeal:
    On or about September 24, 2010, [Dickerson] . . .
    did knowingly possess a machinegun [and a] . . .
    revolver . . . in furtherance of the crime of posses-
    sion of cocaine base (“crack”) with intent to dis-
    tribute it as charged in Count 1 and the crime of
    distribution of cocaine base (“crack”) in Kankakee
    County, Illinois in August of 2010. (emphasis
    added).
    Count 2 also states that these charges, if proven, violate
    18 U.S.C. § 924(c)(1)(A)(i), which provides for a 50-
    4                                              No. 11-3285
    month minimum sentence for persons who “possess[] a
    firearm” “in furtherance of” a drug trafficking crime,
    and 18 U.S.C. § 924(c)(1)(B)(ii), which provides for a 360-
    month minimum sentence if the firearm possessed is
    a machinegun.
    The conjunction “and” in Count 2 in effect divides this
    count into two separate charges, regarding possession
    and distribution. Only the second of these two charges,
    which we have labeled “Count 2, Charge 2,” is relevant to
    this appeal. The separate charges can be broken out as
    follows:
    Count 2, Charge 1:   On or about September 24,
    2010, [Dickerson] . . . did
    knowingly possess a
    machinegun [and a] . . . re-
    volver . . . in furtherance of
    the crime of possession of
    cocaine base (“crack”) with
    intent to distribute it as
    charged in Count 1.
    Count 2, Charge 2:   On or about September 24,
    2010, [Dickerson] did know-
    ingly possess a machinegun
    [and a] . . . revolver . . . in
    furtherance of . . . the crime
    of distribution of cocaine
    base (“crack”) in Kankakee
    County, Illinois in August
    of 2010.
    Before the start of Dickerson’s trial in June 2011, the
    government and Dickerson submitted proposed jury
    No. 11-3285                                                    5
    instructions. The parties agreed on the following instruc-
    tions, which we have labeled ¶¶ 1-2:
    ¶ 1:   A person possesses a firearm “in furtherance
    of” a drug crime if the firearm furthers,
    advances, moves forward, promotes, or
    facilitates a drug trafficking crime. The
    mere presence of a firearm at the scene of a
    crime is insufficient to establish that the
    firearm was possessed “in furtherance of” a
    drug trafficking crime. There must be
    some connection between the firearm and
    the drug trafficking crime.
    ¶ 2:   Some factors that you may consider in deter-
    mining whether a firearm possession was in
    furtherance of a drug crime include, but
    are not limited to: (1) the type of fire-
    arm; (2) whether the firearm was stolen;
    (3) whether the firearm possession was
    legitimate or illegal; (4) whether the firearm
    was loaded; (5) the accessibility of the fire-
    arm; (6) the proximity of the firearm to
    drugs, drug profits, or materials used for
    drug trafficking; (7) the type of drug
    activity that is being conducted; and (8) the
    time and circumstances under which the
    firearm was found.
    Jury instruction ¶ 1 appears to have been adapted from
    what was, at the time, a proposed set of pattern jury
    instructions for use in the trial courts of this circuit, and ¶ 2
    appears to have been derived from the commentary
    6                                              No. 11-3285
    to these proposed pattern instructions. See Pattern
    Criminal Jury Instructions for the Seventh Circuit for
    18 U.S.C. § 924(c)(1)(A) (2012). The court added a third
    instruction, offered by the government over Dickerson’s
    objection, regarding how the possession of a gun could
    be “in furtherance of” the drug crime. This third instruc-
    tion, which we have labeled ¶ 3, reads:
    ¶ 3:   When a defendant receives a gun in ex-
    change for drugs, he takes possession of a
    firearm in a way that furthers, advances,
    and helps forward the distribution of drugs.
    In its closing argument, the government offered two
    theories regarding how Dickerson “possessed” the guns
    “in furtherance” of a drug crime. First, the government
    argued that the revolver recovered at Dickerson’s
    Bourbonnais apartment on September 25 furthered the
    controlled buy between Dickerson and Vankuiken on
    that date. This theory corresponds to Count 2, Charge 1,
    of the indictment. Second, the government asserted that
    the three machineguns and two other guns recovered
    from Dickerson’s storage shed on September 24
    furthered the August guns-for-drugs exchange with
    Vankuiken. This theory corresponds to Count 2, Charge 2,
    of the indictment.
    Dickerson did not raise a claim of variance regarding
    Count 2, Charge 2, during his trial. In other words, he did
    not mention that his charged possession of a machine-
    gun on or about September 24, used in furtherance of
    drug distribution in August, differed from the govern-
    ment’s evidence on this charge, all of which concerned
    No. 11-3285                                             7
    events in August. We also note that Dickerson has not
    challenged Count 2 as duplicitous, either in the district
    court or on appeal.
    The jury found Dickerson guilty on all three counts.
    Concerning Count 2, the jury found that one of the
    firearms that Dickerson possessed in furtherance of a
    drug crime was a machinegun. The court sentenced
    Dickerson to 360 months’ imprisonment on Count 2, the
    mandatory minimum. With additional convictions and
    sentences on Counts 1 and 3, Dickerson faces a total
    sentence of 511 months’ imprisonment.
    II. Discussion
    Dickerson challenges his conviction under 18 U.S.C.
    § 924(c) on three grounds. First, he contends that the
    district court’s jury instructions, specifically ¶ 3, pre-
    sented an inaccurate statement of the law, which preju-
    diced Dickerson. Second, he contends that his dual con-
    victions for selling drugs and, in his words, receiving
    guns as payment for the sale of drugs violate the
    doctrine of merger. Third, he claims that Count 2 of
    the indictment failed to allege an essential element of
    a charge under 18 U.S.C. § 924(c), specifically, that he
    possessed the firearms in August 2010, the month for
    which this count charges him with distribution of crack
    cocaine. We consider Dickerson’s arguments in turn.

    A. Jury Instructions
    We review de novo whether jury instructions
    accurately summarize the law, “but give the district court
    substantial discretion to formulate the instructions . . .
    [provided that the instructions] represent[] a complete
    and correct statement of the law.” United States v. Noel,
    
    581 F.3d 490
    , 499 (7th Cir. 2009) (quoting United States
    v. Matthews, 
    505 F.3d 698
    , 704 (7th Cir. 2007)). Our
    review can be thought of as involving two steps. First,
    we review the legal accuracy of a jury instruction
    de novo. United States v. McKnight, 
    665 F.3d 786
    , 790 (7th
    Cir. 2011) reh’g and suggestion for reh’g en banc denied, 
    671 F.3d 664
    (7th Cir. 2012) and cert. denied, 
    132 S. Ct. 2756
    (2012) reh’g denied, 
    133 S. Ct. 87
    (2012). Second, if we
    determine that that the instruction is legally accurate at
    the first step, we then examine the district court’s particu-
    lar phrasing of the instruction for abuse of discretion.
    
    Id. at 790-91. We
    will reverse at this second step “only if
    it appears both that the jury was misled and that the
    instructions prejudiced the defendant.” 
    Id. at 791 (quoting
    United States v. Curry, 
    538 F.3d 718
    , 731 (7th Cir. 2008)).
    We begin our review by noting that the challenged
    jury instruction accurately reflects this circuit’s caselaw.
    Dickerson objects to the district court instructing the
    jury that “when a defendant receives a gun in exchange
    for drugs, he takes possession of a firearm in a way that
    furthers, advances, and helps forward the distribution
    of drugs.” This instruction mirrors our holding in United
    States v. Doody, 
    600 F.3d 753
    , 755 (7th Cir. 2010). In
    that case, Alduff Doody sold powder cocaine to a con-
    No. 11-3285                                                9
    fidential informant who claimed not to have any cash,
    and instead gave Doody a pistol as collateral. We
    sustained Doody’s conviction under 18 U.S.C. § 924(c),
    holding that, “when a defendant receives a gun for
    drugs, he takes possession of the firearm in a way that
    furthers, advances, or helps forward the distribution of
    drugs.” 
    Doody, 600 F.3d at 755
    . This holding is reflected
    almost verbatim in the district court’s jury instruction
    to which Dickerson objects.
    The Supreme Court has expressly declined to settle the
    issue of whether a guns-for-drugs exchange lies within
    the purview of 18 U.S.C. § 924(c). See Watson v. United
    States, 
    552 U.S. 74
    , 83 (2007) (stating that the view that “a
    drug dealer who takes a firearm in exchange for his
    drugs generally will be subject to . . . [this provision] may
    or may not prevail, and we do not speak to it today”
    (internal quotation marks omitted)). In light of the Su-
    preme Court’s deliberate silence on this issue, our
    holding in Doody is controlling precedent. In the court-
    rooms of this circuit, Doody is the law.
    Dickerson recognizes this fact and urges us to revisit
    that holding. This court “will not reexamine a recent
    decision . . . unless given a compelling reason to do so.”
    Bethesda Lutheran Homes & Servs., Inc. v. Born, 
    238 F.3d 853
    , 858 (7th Cir. 2001). Compelling reasons include
    legislative or regulatory changes, judicial decisions ad-
    dressing related or analogous issues, changes in the
    social or economic context surrounding the decision, or
    other significant, new information. 
    Id. Dickerson does not
    offer any of these reasons to
    support his position. Instead, he offers semantics. He
    10                                            No. 11-3285
    contends that it is a drug dealer’s agreement to accept
    a firearm—not that drug dealer’s later possession of
    it—that facilitates a drug transaction. According to
    Dickerson, the transaction should be considered to
    have been completed by the time he physically pos-
    sessed the firearm.
    The problem with this argument is that it cannot get
    around the fact that, even when a drug dealer does not
    come into possession of the firearm until after the
    drugs were distributed, it is that later possession that
    makes the drug transaction possible. See 
    Doody, 600 F.3d at 756
    . In distinguishing this court’s definition of
    “possession” from Dickerson’s favored interpretation,
    we are not merely parsing words. If Dickerson had
    agreed to accept the firearms, but later reneged on his
    agreement, refusing to take possession, it is hard to
    imagine that he would have allowed Vankuiken
    to keep the drugs. Hence, which item in the exchange
    happened to change hands first is not dispositive in
    determining whether the possession was in furtherance
    of the drug crime. See United States v. Sterling, 
    555 F.3d 452
    , 458 (5th Cir. 2009) (“[D]rug traffickers cannot
    escape liability [under 18 U.S.C. § 924(c)] simply by
    structuring their transactions to arrange for later
    delivery of the firearms.”).
    There are sound policy reasons why Congress would
    want to apply enhanced penalties whenever guns and
    drugs mix, regardless of the temporal order of the ex-
    change. The presence of guns—even, as here, unloaded
    guns which were only present for part of the ex-
    No. 11-3285                                             11
    change—during a drug transaction may increase the
    likelihood of violence erupting in what are often
    already volatile situations. Congress may have been
    concerned that the combined presence of firearms and
    drugs increases the likelihood of violence occurring,
    above the sum of the likelihood of violence in a drugs-
    only situation plus the likelihood of violence occurring
    in a guns-only situation. See Smith v. United States, 
    508 U.S. 223
    , 240 (1993) (“When Congress enacted the [then]
    current version of § 924(c)(1), it was no doubt aware
    that drugs and guns are a dangerous combination.”) This
    potential multiplicative effect could be present even in
    the exchange between Dickerson and Vankuiken, where
    the drugs and firearms components of the exchange
    occurred sequentially.
    The logic undergirding 18 U.S.C. § 924(c) applies even
    where, as here, firearms are employed simply as a
    method of payment. Even when guns serve only an
    instrumental function, that situation could easily
    change, should the drug deal go south. See 
    id. (“The fact that
    a gun is treated momentarily as an item of com-
    merce does not render it inert or deprive it of destructive
    capacity. Rather, as experience demonstrates, it can be
    converted instantaneously from currency to cannon.”).
    Indeed, Congress amended 18 U.S.C. § 924(c) in 1998
    for the specific purpose of expanding the statute to
    cover passive possession of a firearm in furtherance of
    a covered felony. See United States v. O’Brien, 
    130 S. Ct. 2169
    , 2179 (2010) (noting that the 1998 addition of
    the “possession” prong to the statute was “a direct re-
    sponse to this Court’s decision in Bailey v. United States,
    12                                                 No. 11-3285
    
    516 U.S. 137
    (1995) . . . that the word ‘use’ in the pre-
    amendment version of § 924 ‘must connote more than
    mere possession’ ” (citation omitted)).
    In interpreting the “possession in furtherance” prong
    of 18 U.S.C. § 924(c), six of our sister circuits have
    reached the same conclusion as we did in Doody. See
    United States v. Gardner, 
    602 F.3d 97
    , 103 (2d Cir. 2010), cert.
    denied, 
    130 S. Ct. 3372
    (2010); United States v. Mahan,
    
    586 F.3d 1185
    , 1188 (9th Cir. 2009); United States v. Dolliver,
    228 F. App’x 2, 3 (1st Cir. 2007) (per curiam); United States
    v. Luke-Sanchez, 
    483 F.3d 703
    , 706 (10th Cir. 2007);
    United States v. Boyd, 209 F. App’x 285, 290 (4th Cir.
    2006); United States v. Frederick, 
    406 F.3d 754
    , 764 (6th
    Cir. 2005); see also 
    Sterling, 555 F.3d at 458
    (assuming
    without deciding that a guns-for-drugs exchange
    involves possession of a gun to further the sale of drugs).
    Along with our sister circuits, we consider bartering
    firearms for drugs, or vice versa, to be a sufficiently
    specific nexus between these two objects to constitute
    possession in furtherance of the drug sale. For the afore-
    mentioned reasons, we decline to break with our prece-
    dent. The interpretation of “possession in furtherance”
    articulated in Doody remains logically and legally
    sound. Given that the district court’s jury instruction
    accurately reflects our holding in Doody, we conclude
    that it was legally accurate.
    We now move to the second stage of our analysis, in
    which we inquire into whether the district court abused
    its discretion in its particular phrasing of this instruc-
    tion. 
    McKnight, 665 F.3d at 79-91
    . Reversal is warranted
    No. 11-3285                                                 13
    only if it appears that (i) the jury was misled and (ii) the
    instructions prejudiced the defendant. 
    Id. In making these
    determinations, our review is limited to deter-
    mining whether the instructions as a whole, i.e., ¶¶ 1-3,
    were sufficient to inform the jury of the applicable
    law. 
    Curry, 538 F.3d at 731
    .
    Dickerson accepts ¶¶ 1-2 of the jury instructions,
    but objects to ¶ 3. The district court phrased this third
    instruction using nearly identical language as that used
    in Doody. Rather than misleading the jury or prejudicing
    the defendant, this instruction accurately conveyed
    this circuit’s caselaw to the jury. With the validity of ¶¶ 1-2
    not at issue, we conclude that the district court did
    not abuse its discretion in offering these instructions.
    ***
    The conclusory-seeming nature of ¶ 3 suggests that
    the possibility of Sandstrom error may merit some dis-
    cussion. Sandstrom error occurs where the particular
    phrasing of a jury instruction creates either a conclusive
    or a mandatory presumption in the minds of jurors.
    See Sandstrom v. Montana, 
    442 U.S. 510
    (1979). Such errors
    violate the Fifth Amendment’s requirement that the
    government prove every element of a criminal offense
    beyond a reasonable doubt. 
    Id. at 524. It
    is important to
    note that Dickerson does not make a Sandstrom claim.
    Moreover, even if he had raised such a claim, we think
    that any Sandstrom error contained in ¶ 3 would be harm-
    less. Despite the fact that Dickerson waived this argu-
    14                                                    No. 11-3285
    ment,1 and notwithstanding the harmlessness of any
    possible Sandstrom error, we believe that some discus-
    sion of this topic would be helpful, to provide guidance
    to lower courts in crafting instructions in similar cases.
    A conclusive presumption exists where a trial court
    delivers a jury instruction that a reasonable jury could
    interpret as an irrebuttable directive to find a given
    element of a charged offense once convinced of a
    predicate fact or facts triggering the presumption.
    
    Sandstrom, 442 U.S. at 517
    . Such a directive forecloses
    1
    While Dickerson does not expressly argue that ¶ 3 constitutes
    Sandstrom error, two of his statements at least hint at a constitu-
    tional challenge—albeit an undeveloped one—to ¶ 3 as estab-
    lishing a conclusive presumption. In his opening brief,
    Dickerson asserts that “the judge’s instruction ‘When a defen-
    dant receives a gun in exchange for drugs, he takes possession
    of the firearm in a way that furthers . . . the distribution of
    drugs’ compelled the jury to convict [him] if they found
    those facts to be true.” He also objected to ¶ 3 during the jury
    instruction conference in the district court, claiming that this
    language “tak[es] that Doody case . . . and turn[s] it into a rule.”
    Dickerson makes these brief statements without any further
    elaboration, e.g., without referencing concepts such as
    Sandstrom error, conclusive presumptions, or relevant caselaw.
    Assuming that these statements even imply a claim of
    Sandstrom error, such a claim would be waived. See United
    States v. Holm, 
    326 F.3d 872
    , 877 (7th Cir. 2003) (“perfunctory
    and undeveloped arguments, and arguments that are unsup-
    ported by pertinent authority, are waived (even where those
    arguments raise constitutional issues).” (citation omitted)).

    independent jury consideration of whether the facts
    proved are sufficient to establish the relevant element of
    the charged offense. Carella v. California, 
    491 U.S. 263
    ,
    266 (1989) (per curiam). Where “the jury might have
    understood the presumption to be conclusive, . . . the
    instruction was constitutional error.” 
    Id. We need not
    resolve the question of whether ¶ 3
    contains a conclusive presumption, because, even if this
    instruction were deemed unconstitutional, the use of
    this potentially erroneous instruction would constitute
    harmless error under Chapman v. California, 
    386 U.S. 18
    (1967). In assessing a claim of constitutional error, we
    are mindful that “an otherwise valid conviction should
    not be set aside if the reviewing court may confidently
    say, on the whole record, that the constitutional error
    was harmless beyond a reasonable doubt.” Delaware v.
    Van Arsdall, 
    475 U.S. 673
    , 681 (1986). Constitutionally
    erroneous jury instructions are harmless where “the
    predicate facts are so closely related to the ultimate fact
    to be presumed that no rational jury could find those
    facts without also finding that ultimate fact.” United States
    v. Parmelee, 
    42 F.3d 387
    , 393 (7th Cir. 1994) (quoting
    
    Carella, 491 U.S. at 271
    (per curiam) (Scalia, J., concur-
    ring)). “In many cases, the predicate facts conclusively
    establish [the element of the charge], so that no rational
    jury could find that the defendant committed [the
    former] . . . but did not [commit the latter].” Rose v. Clark,
    
    478 U.S. 570
    , 580-81 (1986). In these cases, “the erroneous
    instruction is simply superfluous.” 
    Id. at 581. Dickerson’s
    case fits this mold precisely. We held in
    Doody that a guns-for-drugs exchange constitutes posses-
    16                                             No. 11-3285
    sion in furtherance for purposes of 18 U.S.C. § 
    924(c). 600 F.3d at 755
    . Importantly, we did not state that a
    district court was within its discretion in making such
    a finding, or that such a finding does not rise to the
    level of reversible error. Instead, we stated plainly that
    a guns-for-drugs exchange is possession in furtherance.
    
    Id. In other words,
    the predicate fact that a defendant
    traded drugs for guns conclusively establishes that the
    possession in furtherance prong of 18 U.S.C. § 924(c)
    is met. Thus, even if ¶ 3 could be characterized as in-
    volving a conclusive presumption, this possibly flawed
    wording merely would render the instruction super-
    fluous. See 
    Rose, 478 U.S. at 581
    .
    Courts’ concerns regarding Sandstrom error are moti-
    vated by the requirement that the government prove
    every element of the charged crime beyond a reasonable
    doubt. 
    Id. at 580. That
    requirement, in turn, helps ensure
    that only the guilty are punished. 
    Id. It follows that
    when a guilty verdict “reached in a case in which
    Sandstrom error was committed is correct beyond a rea-
    sonable doubt, reversal of the conviction does nothing
    to promote the interest that the rule serves.” 
    Id. Since the challenged
    instruction reflects our controlling
    Doody precedent, one cannot say that a guilty verdict
    potentially based in part on this instruction failed to
    meet this standard. Therefore, “[i]t would further
    neither justice nor the purposes of the Sandstrom rule to
    reverse a conviction in such a case.” 
    Id. at 581-82. If
    any
    Sandstrom error in ¶ 3 may be found, such error is harm-
    less.
    No. 11-3285                                              17
    While we find that the district court accurately sum-
    marized the law in this circuit, acted within its discretion
    in promulgating this instruction, and did not commit
    any non-harmless Sandstrom error, we also are mindful
    not to endorse the district court’s particular phrasing of
    ¶ 3. Trial courts should craft jury instructions so as
    avoid wordings that could be interpreted as creating
    conclusive or mandatory presumptions. In this particular
    case, Dickerson waived any claim regarding Sandstrom
    error and, even if he had not done so, the district
    court’s use of ¶ 3 amounts, at most, to harmless error.
    Still, in the future it would behoove the courts of this
    circuit to avoid phrasings that even raise the specter of
    Sandstrom error. In some circumstances, instructing a
    jury that it may consider whether a firearm was used
    as an object of barter in a drug exchange as a factor in
    determining whether the firearm was possessed in fur-
    therance of the drug crime may be more appropriate
    than the language used here. See Committee Comment
    to Pattern Criminal Jury Instructions for the Seventh
    Circuit for 18 U.S.C. § 924(c)(1) (2012) (second paragraph
    of comment to the “definition of ‘in furtherance’ ” instruc-
    tion). For purposes of this case, however, it suffices to
    say that Doody’s direct holding that such an exchange
    constitutes possession in furtherance makes this infer-
    ence overpowering. Cf. 
    Rose, 478 U.S. at 581
    .
    B. Dickerson’s Merger Defense
    Dickerson argues that his conviction under 18 U.S.C.
    § 924(c) following these jury instructions, when coupled
    18                                             No. 11-3285
    with his conviction for the baseline offense of drug traf-
    ficking, violates the doctrine of merger. See United States
    v. Gaddis, 
    424 U.S. 544
    , 547 (1976) (holding that a
    defendant cannot be convicted of both robbing a bank
    and receiving the proceeds of that robbery). Dickerson
    is mistaken, however, in viewing his convictions for
    drug trafficking and possession of a firearm in fur-
    therance of drug trafficking as two sides of the same
    coin, akin to being punished for committing a criminal
    act and receiving the proceeds of that act. Instead, 18
    U.S.C. § 924(c) punishes a harm not covered by the stan-
    dard drug trafficking statute. Dickerson’s decision to
    receive his payment in the form of guns increases
    the potential for violence by introducing a deadly
    weapon into a situation in which violence is not infre-
    quent. Moreover, while the doctrine of merger typically
    applies where “Congress . . . did not intend for pyra-
    miding of penalties,” United States v. Fleming, 
    504 F.2d 1045
    , 1052 (7th Cir. 1974), a simple reading of 18 U.S.C.
    § 924(c) shows that the statute’s very purpose was to en-
    hance the combined penalty for certain drugs-plus-
    guns offenses, above the sum of the penalties for the
    separately committed drug and gun crimes. See Harris
    v. United States, 
    536 U.S. 545
    , 576 (2002) (noting that the
    statute’s “penalty range becomes harsher” for proscribed
    conduct involving both drugs and guns). The heightened
    potential for violence when guns and drugs mix, as
    discussed above, provides a convincing rejoinder to
    Dickerson’s claim that his conviction violates the doc-
    trine of merger.
    No. 11-3285                                                19
    C. Variance between the           Indictment     and    the
    Evidence Offered at Trial
    Dickerson also challenges his conviction under Count 2
    for knowing possession of a machinegun “on or about
    September 24, 2010,” in furtherance of drug trafficking
    in August 2010. This subsection of this count is labeled
    Count 2, Charge 
    2, supra
    . Evidence adduced at trial indi-
    cates that Dickerson’s machineguns remained in his
    storage unit from the time he received them from
    Vankuiken in August until the police discovered them
    on September 24. Thus, a more precisely worded indict-
    ment would have inserted August 2010 as the relevant
    date in both elements of this charge.
    Dickerson argues that this discrepancy in the two
    dates calls into question the legal sufficiency of his indict-
    ment, and directs us to caselaw concerning the omission
    of an essential element in an indictment. We think that
    his argument is better characterized as a variance claim.
    A variance occurs “when the facts proved at trial differ
    from those alleged in the indictment.” United States v.
    Longstreet, 
    567 F.3d 911
    , 918 (7th Cir. 2009). A difference
    between the date charged in an indictment and the
    date proven at trial is “a classic variance, which does not
    change the nature of the crime alleged.” United States v.
    Krilich, 
    159 F.3d 1020
    , 1027 (7th Cir. 1998). We also
    classify as a variance a situation in which the scope of
    the indictment is broader than that of the elements
    proven at trial. See United States v. Willoughby, 
    27 F.3d 263
    , 265 (7th Cir. 1994). The circumstances here bear a
    resemblance to both of these forms of variance. Whether
    20                                              No. 11-3285
    one views the discrepancy between Count 2 and the
    evidence offered at trial as the substitution of one date
    for another, as in Krilich, or as involving the proof of a
    narrower element—i.e., the specific date of Dickerson’s
    firearm possession—in place of the broader “on or
    about” language in the indictment, similar to Willoughby,
    this discrepancy is properly categorized as variance.
    Variance claims are subject to harmless error review.
    United States v. Thompson, 
    23 F.3d 1225
    , 1230 (7th Cir.
    1994). To prevail, Dickerson must show both (i) that the
    evidence presented at trial did not support the jury’s
    verdict on Count 2, and (ii) that the variance prejudiced
    him. United States v. Dean, 
    574 F.3d 836
    , 842 (7th Cir.
    2009). Thus, we treat a claim of variance as a challenge
    to the sufficiency of the evidence. United States v.
    Hewlett, 
    453 F.3d 876
    , 879 (7th Cir. 2006). In evaluating
    such a claim, we view the evidence in the light most
    favorable to the government. 
    Id. We will “overturn
    a
    conviction only if the record contains no evidence
    from which a reasonable juror could have found the
    defendant guilty.” 
    Longstreet, 567 F.3d at 918
    .
    An imprecise date alleged in an indictment generally
    constitutes harmless variance, unless a specific date is
    an essential or material element of the alleged offense.
    United States v. Auerbach, 
    913 F.2d 407
    , 411 (7th Cir. 1990).
    The date of the alleged crime is considered essential or
    material where the precise date is “necessary to establish
    the very illegality of the behavior and thus the court’s
    jurisdiction.” United States v. Cina, 
    699 F.2d 853
    , 859
    (7th Cir. 1983). This level of precision is not needed
    No. 11-3285                                             21
    here; Dickerson’s actions were just as unlawful in
    August 2010 as they were in September. Because the
    precise date was not a crucial component of the charge,
    we think Dickerson’s action in August 2010 could fairly
    be considered part and parcel of this charge. See United
    States v. Synowiec, 
    333 F.3d 786
    , 790 (7th Cir. 2003).
    Where, as here, the date is not an essential or material
    element of the charged offense, “it is generally sufficient
    to prove that the offense was committed on any day
    before the indictment and within the statute of limita-
    tions.” United States v. Leibowitz, 
    857 F.2d 373
    , 378 (7th
    Cir. 1988). We have applied this general rule in cases
    where the interval between the date in the indictment
    and the date for which the prosecution offered evidence
    at trial was longer than in the instant case. See 
    Krilich, 159 F.3d at 1027
    (finding a difference of over one year
    between the two dates to be harmless variance);
    
    Auerbach, 913 F.2d at 411-13
    (variance of no less
    than two months is not sufficient to reverse). Con-
    sistent with this caselaw, we find the evidence presented
    at Dickerson’s trial sufficient to support the jury’s
    verdict, the discrepancy between these two dates not-
    withstanding.
    Neither did this variance prejudice Dickerson. The use
    of the phrase “on or about September 24, 2010” (emphasis
    added), in Charge 2 placed Dickerson on notice that
    the government could introduce evidence regarding
    alleged activities on dates other than September 24.
    
    Leibowitz, 857 F.2d at 379
    (“Where the indictment alleges
    that an offense occurred ‘on or about’ a certain date, the
    defendant is deemed to be on notice that the charge is
    22                                             No. 11-3285
    not limited to a specific date. He therefore cannot make
    the requisite showing of prejudice simply on the fact
    that the government has failed to prove a specific date.”).
    The inclusion of this “on or about” designation in
    the indictment should have signaled to Dickerson
    that the indictment date was approximate and subject
    to reasonable variation. United States v. McKinney, 
    954 F.2d 471
    , 480 (7th Cir. 1992). Dickerson has not argued
    that this variation impeded his ability to present his
    defense or otherwise prejudiced him, and we fail to see
    how it could have done so.
    Since the variance between the date listed in Count 2
    of the indictment and the date for which the govern-
    ment offered evidence at trial was harmless, dismissal
    on this charge is not warranted.
    III. Conclusion
    For the foregoing reasons, we A FFIRM the judgment.
