Opinion for the court filed by Circuit Judge GARLAND.
A jury convicted defendant Juan Petis McLendon of several narcotics offenses. At trial, although the district court had barred the government from presenting testimony about the defendant’s involvement with guns, a government witness testified that he had found ammunition in the defendant’s bedroom. McLendon’s sole contention oh appeal is that the court abused its discretion in denying his motion for a mistrial following that testimony. We conclude that the court did not abuse its discretion, and we therefore affirm the defendant’s conviction.
I
In January 1999, a federal grand jury in the 'District of Columbia indicted McLen-don for the following crimes: (i) three counts of using a telephone to facilitate the distribution of cocaine base, in violation of 21 U.S.C. § 843(b); (ii) three counts of distributing 50 or more grams of cocaine base, in violation of 21 U.S.C. § 841(a)(1) and (b)(1)(A); (iii) three counts of distributing 50 or more grams of cocaine base within 1000 feet of a school, in violation of 21 U.S.C. § 860(a); (iv) one count of carrying a firearm during a drug trafficking offense, in violation of 18 U.S.C. § 924(c)(1); (v) one count of assaulting and resisting a police officer, in violation of D.C.Code § 22-505(a) (1999); and (vi) one count of carrying a pistol without a license, in violation of D.C.Code § 22-3204(a) (1999).
McLendon’s first trial began on February 23,1999. It ended with the return of a partial verdict of not guilty on the firearms counts, as well as on the charge of assaulting an officer. The court declared a mistrial as to the remaining counts.
In March 1999, the grand jury returned a superseding indictment containing the remaining counts from the first indictment as well as additional violations of 21 U.S.C. §§ 843(b), 841(a)(1) and (b)(1), and 860. That case went to trial in July 1999. It ended in a mistrial after the jury was unable to reach a verdict on any count.
A third trial — the subject of this appeal — began on January 4, 2000. That trial ended with a guilty verdict on all counts. After various procedural delays, *1111 McLendon was sentenced to a total of 235 months’ incarceration on February 22, 2002.
The government’s trial evidence showed that, in the spring of 1998, McLendon asked his friend Gloria Pearson to help him find customers to whom he could sell drugs. Unfortunately for McLendon, Pearson was working as a confidential informant for the United States Park Police. Pearson reported McLendon’s request to the police, who recorded a telephone call in which Pearson arranged for McLendon to sell a half ounce of crack cocaine to her “girlfriend’s husband” — who was, in fact, Detective Richard White. 1/6/00 Tr. at 82. On July 6, 1998, McLendon drove to a parking lot in Washington, D.C., where he met Pearson and White in White’s car. There, he gave White approximately half an ounce of crack in exchange for $600. The entire transaction was videotaped by two cameras, one inside White’s car and another in a nearby police van.
Following this initial transaction, McLendon started communicating directly with White. To -arrange further deals, McLendon called and paged White regularly. These calls resulted in four more transactions between July 9, 1998 and September 17, 1998, in each of which McLen-don gave White approximately 62 grams of crack in exchange for $1900. Each transaction took place in White’s parked car, and each was taped. After the final transaction on September 17, 1998, McLendon was arrested on the scene. Later that day, the police searched McLendon’s bedroom in his mother’s house in Maryland and recovered, among other things, a paper bag containing crack cocaine residue, a mirror with a razor blade, a digital scale, hundreds of small ziplock bags, and several rounds of ammunition. The following-day, the police searched McLendon’s car, where they found a plastic bag of cocaine base.
McLendon testified in his own defense. He did not deny that he exchanged- crack for cash, but contended that he had been entrapped into doing so. McLendon testified that he was an intimate friend of Gloria Pearson, who told him that she needed his help in obtaining money for drugs. According to McLendon, Pearson said that she had sold drugs to her girlfriend’s husband, but that he had not paid her for them. Pearson allegedly told McLendon that she wanted the husband to think the drugs were coming from McLen-don, because she thought that would ensure that the husband would pay. McLen-don said he only agreed to help after Pearson said her mother had cancer. According to McLendon, Pearson provided all of the drugs that he sold to White; McLendon only pretended they were his. The defendant also said that after each transaction, he turned over to Pearson all of the money that White had paid him, keeping only enough for gas and haircuts.
Before the third trial began, McLen-don’s lawyer complained that witnesses in the second trial had made remarks about guns despite the district court’s decision ■ — • midway through the second trial —• to exclude such testimony. The court reiterated its instruction barring testimony “about guns.” 1/4/00 Tr. at 6. Thereafter, on the second day of the third trial, Investigator Anastasios Kapetanakos testified about what he had found in his search of McLendon’s bedroom. After Kapetanakos listed a number of drug-related items, the prosecutor asked whether there was “anything else recovered.” 1/5/00 Tr. at 178. The investigator answered that he had also recovered “several rounds of ammunition.” Id. The court immediately interrupted the testimony and instructed the jury to “[disregard that reference to ammunition.” Id. 1
McLendon’s lawyer approached the bench and moved for a mistrial. The dis *1112 trict court denied the request, stating that it would give a “more powerful curative instruction.” Id. The court then advised the jury as follows: “[A]gain I remind you Mr. McLendon, first of all, is not charged with possession of any contraband recovered from that home, and he’s certainly not charged with possession of any ammunition, and I instruct you to disregard that question and disregard the answer.” Id. at 179. Employing a leading question, the prosecutor then went on to elicit the fact that the investigator had also found a ledger in McLendon’s bedroom, id., a ledger shown to contain Detective White’s pager number. 2
At several points later in the trial, the court discussed the investigator’s mention of ammunition and what should be done about it. The court stated that it believed the prosecutor’s representation that he had told the witness not to mention weapons, and concluded that the witness had done so either intentionally or negligently. 1/7/00 a.m. Tr. at 104-08. In the end, however, the court found that the “[o]ne isolated reference to the ammunition is something that can be disregarded” by the jury. Id. at 106. The trial continued without further reference to ammunition, and the jury returned a guilty verdict against McLendon on all counts.
McLendon now appeals. His sole claim is that the trial judge erred in refusing to grant a mistrial in light of the investigator’s mention of the ammunition.
II
We review the trial judge’s denial of McLendon’s motion for a mistrial only for an abuse of discretion.
United States v. Gartmon,
First, there was nothing unfairly prejudicial, per se, about the investigator’s testimony that he had recovered ammunition from McLendon’s room.
See United States v. Gloster,
Of course, the district court did not initially admit the gun evidence, but rather excluded it under Federal Rule of Evidence 403 on the ground that the danger of unfair prejudice outweighed the evidence’s probative value. 7/13/99 Tr. at 61;
see
Fed.R.Evid. 403. The court reached that conclusion, it said, because the defendant had been acquitted of gun charges in the first trial and was not charged with a gun crime in the superseding indictment. 7/13/99 Tr. at 58-61. The former point is inapposite because the ammunition recovered from the bedroom was unrelated to the charges of which McLendon had been acquitted at the first trial,
5
and both points ignore the case law permitting admission of gun evidence as probative of narcotics violations.
See supra
note 4. Nonetheless, we review a court’s determination under Rule 403 “most deferentially.”
Gartmon,
But we also review most deferentially a district judge’s decision to deny a mistrial, and we should not lose sight of the fact that the same judge who initially weighed the Rule 403 balance against admission of the evidence, subsequently determined that the investigator’s testimony did not warrant a mistrial. Hence, even if the investigator’s testimony ivere unfairly prejudicial, the judge’s description of that testimony as “one isolated reference to the ammunition” was accurate, and his conclusion that it was “something that can be disregarded” by the jury is one to which we defer. 1/7/00 a.m. Tr. at 106.
This brings us to the second factor in our analysis, the district court’s curative instructions. Immediately upon hearing the investigator’s reference to ammunition, the court cut off the witness and told the jury to “[disregard that reference to ammunition.” 1/5/00 Tr. at 178. It then followed up with a sterner admonition, reminding the jury that McLendon was “not charged with possession of any ammunition” and instructing the jurors “to disregard that question and disregard the answer.” Id. at 179. During final jury instructions, the court further in *1114 structed, without mentioning ammunition, that “[i]f, after a witness answered a lawyer’s question, I ruled that the answer should be stricken, you should disregard both the question and the answer in your deliberations.” 1/7/00 p.m. Tr. at 37.
In denying the motion for a mistrial, the district court reasoned that the jury “can follow instructions to disregard testimony.”
Id.
at 107. Both the Supreme Court and this court have presumed the same thing.
6
Given the brevity of the offending testimony and the clarity of the district court’s instructions, we have no reason to doubt the validity of that presumption in this case.
See United States v. Burroughs,
Finally, in determining the impact of unfairly prejudicial evidence on a jury, we weigh the
extent
of that prejudice against the strength of the admissible evidence. See
Eccleston,
McLendon contends that his testimony regarding his friendship with Pearson and her mention of her mother’s cancer was sufficient to show “inducement.” We need not decide whether McLendon is correct,
8
however, given the strength of the government’s evidence of McLendon’s predisposition.
See United States v. Hanson,
In light of this strong evidence of McLendon’s guilt, coupled with the judge’s curative instructions, we conclude that the impact of the investigator’s brief reference to ammunition was, if anything, de minimis. McLendon resists this conclusion, contending that the testimony regarding ammunition was the only evidence that differed between the second and third trials,
10
and that it therefore must be regarded as having been the decisive factor. But as we have cautioned in the past, the fact that a case previously ended in a mistrial is not sufficient to establish that the case was close.
See United States v. Williams,
In sum, even if we were to regard the investigator’s mention of ammunition as unfairly prejudicial, the extent of that prejudice was insignificant in light of the court’s curative instructions and the weight of the admissible evidence.
Ill
For the foregoing reasons, we conclude that the district court did not abuse its discretion in denying McLendon’s motion for a mistrial. Accordingly, the judgment of the district court is
Affirmed.
Notes
. The court apparently interpreted its prior instruction barring testimony "about guns” as *1112 including ammunition, 1/4/00 Tr. at 6, an interpretation the government does not dispute.
. The government explains that it was this evidence, and not testimony concerning the ammunition, that the prosecutor had been attempting to elicit by asking the investigator whether he had recovered "anything else.” Appellee's Br. at 14.

See, e.g., United States v. Brown,
.
See United States v. Dunn,
.Those charges were for carrying a firearm during a drug trafficking offense and carrying a pistol without a license, both premised on a gun that McLendon allegedly had on his person at the time of his arrest.

See United States v. Neville,
. Although it is true that the investigator did not refer to the ammunition during the second trial, several witnesses at that trial did refer to McLendon's connection to guns. See 7/13/99 Tr. at 13 (Detective White); 7/14/99 Tr. at 21-22 (Gloria Pearson); 7/19/99 Tr. at 66 (defendant McLendon).
