Before Wiener, Willett, and Douglas, Circuit Judges. Dana M. Douglas, Circuit Judge: Jacob Ray Owens pleaded guilty to conspiracy to possess with intent to distribute 50 grams or more of actual methamphetamine. The district court sentenced him to 324 months of imprisonment, followed by a five-year term of supervised release. Pursuant to 28 U.S.C. § 2255, Owens challenges his sentence, arguing that his trial and appellate counsel were ineffective for failing to object to the purity of methamphetamine attributed to him. In denying habeas relief, the district court held that Owens failed to show that he was prejudiced by his counsels performance. For the following reasons, we AFFIRM. I. In August 2018, Drug Enforcement Administration (DEA) agents began to investigate Owenss co-conspirator Brian Edward Stowe for trafficking methamphetamine. A few months later, Owens and other co-conspirators were driving through Arizona when police officers conducted a traffic stop, found 10.6 ounces of methamphetamine in the car, and arrested them. While in custody, Owens called Stowe and said they need to get to work and get things going when he gets released. Owens also called other co-conspirators to discuss how Stowe would salvage the business. At a second traffic stop, on November 28, 2018, police officers discovered one of the co-conspirators with methamphetamine. The co-conspirator confessed that he or she had traveled with Stowe and another individual to Tijuana, Mexico, during Thanksgiving to retrieve methamphetamine. A DEA lab report confirmed that the co-conspirator possessed about 205.5 grams of 98% pure methamphetamine, equivalent to 201.3 grams of actual methamphetamine. On January 2, 2019, officers arrested Stowe. He confessed that he partnered with Owens to import and sell methamphetamine. For sourcing methamphetamine, Stowe told officers that he uses an individual that Owens did not. Stowe further admitted that he, Owens, and another co-conspirator purchased five pounds of methamphetamine during a trip to Tijuana, Mexico, on an undisclosed date. Stowe confessed that he made at most six trips to Tijuana, Mexico, and transported about nine to ten pounds total of methamphetamine. A grand jury charged Owens and Stowe with conspiring to possess with intent to distribute 50 grams or more of actual methamphetamine. Owens pleaded guilty without a plea agreement. In the PSR, the probation officer determined that Owens was responsible for at least 2.56 kilograms of actual methamphetamine. That figure is based only on the 10.6 ounces of methamphetamine seized from Owens during his arrest on November 5, 2018, and the five pounds of methamphetamine that he jointly transported with Stowe from Mexico. The DEA did not test the purity of the methamphetamine attributed to Owens. Because the district court found Owens accountable for at least 1.5 kilograms but less than 4.5 kilograms of actual methamphetamine, his base offense level was 36. See U.S.S.G. § 2D1.1(a)(5), (c)(2). With a total offense level of 37 and a criminal history category of V, Owenss Sentencing Guideline range was 324 to 405 months.[1] A. At sentencing, Owenss trial counsel objected to, inter alia, the quantity of actual methamphetamine attributed to Owens. Specifically, his trial counsel contended that the PSR referenced two incidents on November 28, 2018, and January 2, 2019that occurred after Owenss arrest and were thus not attributable to Owens. The probation officer clarified that [n]o drugs from November 28, 2018, or January 2, 2019, were attributed to Owens. Owenss counsel never objected that the 2.56 kilograms of methamphetamine attributed to Owens was not the same purity as the methamphetamine seized on November 28. The court adopted the PSRs findings and application of the Guidelines and accordingly sentenced Owens to 324 months in prison, followed by five years of supervised release. B. On direct appeal, Owenss appellate counsel moved for summary disposition and raised an as-applied Sixth Amendment sentencing challenge, which he conceded was foreclosed by our precedent.[2] Specifically, Owenss appellate counsel raised whether it was a violation of the Sixth Amendment for the district court, relying on Stowes confessions, to attribute the five pounds of methamphetamine to Owens. He argued that Stowes admission was neither Owenss admission nor found by a jury. Instead, it was a judge-found fact that had increased Owenss Sentencing Guidelines range from210 to 262 months to 324 to 405 months. Because that argument is foreclosed by United States v. Hernandez, 633 F.3d 370, 374 (5th Cir. 2011), this court affirmed the district courts judgment. The Supreme Court denied Owenss petition for a writ of certiorari. C. Owens subsequently filed a 28 U.S.C. § 2255 motion in the district court, alleging that his trial and appellate counsel were ineffective for failing to challenge the purity of methamphetamine attributed to him. The district court denied Owenss motion because he failed to show that he was prejudiced by any deficient performance. Further, the district court concluded that the sentencing judge did not commit clear error by inferring that the methamphetamine attributed to Owens had the same purity as the methamphetamine seized from his co-conspirators on November 28, 2018. The district court explained that (1) the purity of the methamphetamine seized on November 28 was supported by reliable evidence, including a DEA lab report; (2) the methamphetamine was seized from within the same conspiracy; and (3) Owens did not meet his burden of rebutting this PSR information as materially untrue, inaccurate, or unreliable. The district court concluded that an evidentiary hearing was unnecessary because the record conclusively showed that Owens was not entitled to relief on any of his claims. Accordingly, the district court denied the § 2255 motion without a hearing, dismissed his action with prejudice, and denied issuance of a certificate of appealability (COA). Owens filed a timely notice of appeal. This court granted a COA for both of his ineffective-assistance claims. We have jurisdiction under 28 U.S.C. §§ 1291 and 2253(c)(1). See Gonzalez v. Thaler, 565 U.S. 134, 14142 (2012). II. When evaluating the denial of a § 2255 motion, the court of appeals reviews factual findings for clear error and conclusions of law de novo. United States v. Phea, 953 F.3d 838, 841 (5th Cir. 2020) (per curiam) (citing United States v. Olvera, 775 F.3d 726, 72829 (5th Cir. 2015)). A claim of ineffective assistance of counsel is a mixed question of law and fact that this courtreviews de novo. Id. (citing United States v. Rivas-Lopez, 678 F.3d 353, 356 (5th Cir. 2012)). An ineffective-assistance-of-counsel claim may be brought in a collateral proceeding under § 2255, whether or not the petitioner could have raised the claim on direct appeal. Massaro v. United States, 538 U.S. 500, 504 (2003). We analyze Owenss claim under the two-pronged test set forth in Strickland v. Washington, 466 U.S. 668, 687 (1984). To prevail, Owens must show that (1) his counsels performance was deficient and (2) the deficient performance prejudiced the defense. See id. To establish deficient performance, he must prove that his counsels assistance fell below an objective standard of reasonableness. United States v. Conley, 349 F.3d 837, 841 (5th Cir. 2003) (quoting Strickland, 466 U.S. at 688). And to establish prejudice, Owens must show that there is a reasonable probability that, but for counsels unprofessional errors, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome. See Strickland, 466 U.S. at 694. Effective appellate counsel should not raise every nonfrivolous argument on appeal, but rather only those arguments most likely to succeed. See United States v. Massey, 79 F.4th 396, 401 (5th Cir. 2023) (quoting Davila v. Davis, 582 U.S. 521, 533 (2017)). Appellate counsel is responsible for making solid, meritorious arguments based on directly controlling precedent. Id. (quoting Conley, 349 F.3d at 841). Owens requests that we vacate his sentence because his trial and appellate counsel were constitutionally ineffective for failing to object to the finding that the 2.56 kilograms of methamphetamine attributed to him was actual methamphetamine, instead of a mixture containing methamphetamine. Owenss Strickland claim fails if he cannot establish either the deficient performance or prejudice prong; a court need not evaluate both if he makes an insufficient showing as to either. See Blanton v. Quarterman, 543 F.3d 230, 235 (5th Cir. 2008). Our Strickland inquiry begins with whether Owenss trial and appellate counsel were deficient. The district court determined that Owenss counsel may have provided deficient performance by failing to object regarding the purity of methamphetamine attributed to Owens. The Government does not challenge the district courts ruling regarding the deficiency prong and relies solely on the prejudice prong. Because Owens fails to show prejudice, as discussed below, we need not address whether Owenss counsel may have been deficient. Owens contends that, if his trial and appellate counsel had objected to the lack of evidence regarding the purity of methamphetamine attributed to him, there is a reasonable probability that he would not have received a base offense level of 36, which was calculated based on him having at least 1.5 kilograms of actual methamphetamine, and that he would have received a lesser sentence based on a mixture of, rather than actual, methamphetamine. He argues that the district court erred when analyzing Stricklands prejudice prong by (1) disregarding the reasonable-probability standard; (2) concluding, without holding an evidentiary hearing, that the government could have proven the purity of methamphetamine; and (3) basing that conclusion on the purity of methamphetamine that was seized from a conspiracy that was outside of Owenss conspiracy. Relevant here, the Guidelines provide that: Methamphetamine (actual) refer[s] to the weight of the controlled substance, itself, contained in the mixture or substance . . . . In the case of a mixture or substance containing . . . methamphetamine, use the offense level determined by the entire weight of the mixture or substance, or the offense level determined by the weight of the . . . methamphetamine (actual), whichever is greater. U.S.S.G.§ 2D1.1(c), n.B (U.S. Sentg Commn 2018) (emphasis added). In other words, [r]egardless of the language of the indictment, the Guidelines advise the district court to apply the offense level determined by the weight of the pure methamphetamine in the mixture or substance if doing so would result in a higher offense level. United States v. Aparicio, 963 F.3d 470, 475 (5th Cir. 2020) (emphasis added) (citing U.S.S.G. § 2D1.1(c), n.(B); United States v. Molina, 469 F.3d 408, 414 (5th Cir. 2006)). The district courts factual findings of the amount of drugs involved must be supported by what it could fairly determine to be a preponderance of the evidence. United States v. Sherrod, 964 F.2d 1501, 1508 (5th Cir. 1992). When making factual findings for sentencing purposes, district courts may consider any information which bears sufficient indicia of reliability to support its probable accuracy. United States v. Harris, 702 F.3d 226, 230 (5th Cir. 2012) (per curiam) (internal quotation marks and citation omitted). Generally, a PSR bears sufficient indicia of reliability to be considered as evidence by the sentencing judge in making factual determinations. Id. (internal quotation marks and citation omitted). Thus, the court may adopt the facts contained in a PSR without further inquiry if those facts have an adequate evidentiary basis with sufficient indicia of reliability and the defendant does not present rebuttal evidence or otherwise demonstrate that the information in the PSR is unreliable. Id. (internal quotation marks and citation omitted) (alteration adopted). Accordingly, we afford significant discretion to the sentencing court in calculating drug quantity and qualit y under the Guidelines. See, e.g., United States v. Dinh, 920 F.3d 307, 313 (5th Cir. 2019) (explaining that a district court properly used samples of a mixture of drugs to calculate overall drug quantity for sentencing); United States v. Lucio, 985 F.3d 482, 48588 (5th Cir. 2021) (finding that a district court permissibly calculated drug quantity and purity based on cryptic text messages). And we give the district court wide latitude in our review for clear error. See United States v. Betancourt, 422 F.3d240, 248 (5th Cir. 2005)(quoting United States v. Cothran, 302 F.3d 279, 287 (5th Cir. 2002)). As a fact finding, the calculation is entitled to considerable deference and will not be reversed as long as it is plausible in light of the record as a whole. Lucio, 985 F.3d at 485 (quoting United States v. Koss, 812 F.3d 460, 466 (5th Cir. 2016)). Because the 205.5 grams seized from Stowes co-conspirator in the scope of the conspiracy was 98% pure, the district court could properly find at the very least that the five pounds attributed to Owens were also 98% pure which means that Owens was accountable for at least 1.5 kilograms of actual methamphetamine and was thus properly sentenced to a within-Guidelines sentence of 324 months imprisonment. Consider the following uncontested information from the PSR. The PSR shows that Stowe and Owens participated in the same larger conspiracy to traffic methamphetamine. While in jail, Owens placed multiple calls to Stowe and told him that they need to get things going when he gets released. Owens also made calls to other co-conspirators and they discussed how Stowe would salvage the business. A co-conspirator told police that he/she, an unknown female, and Stowe made a trip to Tijuana, Mexico, to obtain the 98%-pure methamphetamine. Owens did not dispute any of these facts in the PSR. That trip and its 98%-pure methamphetamine werethusreasonablypartofthebroaderconspiracyinvolvingbothStoweand Owens. The PSR also establishes that Stowe, Owens, and another conspirator picked up five pounds of methamphetamine in Tijuana, Mexico. Owens does not contest this fact, either. The dissent correctly notes that the PSR says that Stowe reported he has a Mexican contact [singular] and a conspirator met the contacts [plural] in Tijuana during their trip, in which they obtained the 98%-pure methamphetamine. But we disagree that this renders the PSR unreliable and the district courts inferences and sentence improper. The PSR elsewhere says, with no uncertainty, that Stowe utilizes an individual (not Owens individual) to find him methamphetamine. That distinguishes this case from our unpublished, nonbinding decision in United States v. Majors, Nos. 20-40405 & 20-40656, 2022 WL 301545 (5th Cir. Feb. 1, 2022) (per curiam), cited by the dissent. There, we concluded that the PSRs lack[ed] an evidentiary basis for $500,500 in restitution because they stated that the victim lost $482,000 and then, elsewhere, that the victim lost $460,000 that is, it gave two different estimates, neither of which justified the full $500,500requested.Id.at*2(internalquotationmarksandcitationomitted). By contrast, Owenss PSR twice conveys Stowes admissions that he has a contact or individual in Tijuana, Mexico. Owens offers no rebuttal evidence on this point. The district court need not rule out every possible alternative conclusion where, as here, its drug quality and quantity findings are supported by the available information. See, e.g., United States v. Cooper, 274 F.3d230, 239(5th Cir.2001)(noting that the heroin conceivably could have been destined for others but concluding that that [t]here is no clear error in the district courts findings because other evidence made it not implausible that the heroin was meant for Cooper and Faulk). Moreover, our deference to the district court is such that the court can consider the statements of coconspirators . . . even statements that are somewhat imprecisein calculating drug quantity. See United States v. Kearby, 943 F.3d 969, 974(5th Cir. 2019) (citing United Statesv. Alford, 142 F.3d 825, 832 (5th Cir. 1998)); see also United States v. Arayatanon, 980 F.3d 444, 451 (5th Cir. 2020) ([T]he drug-quantity determination in the PSR is sufficiently reliable even if based on a coconspirators imprecise testimony, especially absent any competent rebuttal evidence from [the defendant] . . . .); United States v. Cantu-Ramirez, 669 F.3d 619, 629 (5th Cir. 2012) (affirming district courts reliance on co-conspirators testimony in calculating the quantity of drugs involved in an offense); United States v. Rico, 864 F.3d 381, 386 (5th Cir. 2017) (Statements by coconspirators are sufficiently reliable to form the basis of a finding.). [T]o find that evidence . . . unreliable for sentencing purposes, where the governments burden of proof is by a preponderance of the evidence, would automatically call into question the validity of Owenss conviction, which is not at issue on this appeal. See Cantu-Ramirez, 669 F.3d at 629. For these reasons, it is plausible in light of the record as a whole that the five pounds of marijuana attributed to Owens were obtained from Stowes contact in Tijuana and thus also 98% pure, yielding at least 1.5 kilograms of actual methamphetamine. See Lucio, 985 F.3d at 485 (citation omitted). The district court properly distinguished United States v. Rios Baltazar,831F.Appx682,68283(5thCir.2020)(percuriam).Inthatcase, this court held that a district court committed reversible plain error by finding that a defendant had possessed actual methamphetamine, rather than a mixture containing methamphetamine, because [t]here was no information in the PSR supporting the finding. Id. Due to the lack of supporting information such as lab results, admissions, or any discussion of the methamphetamines purity this court determined that the PSRs factual assertion that the drug quantity . . . was actual methamphetamine did not have an adequate evidentiary basis with sufficient indicia of reliability to support its probable accuracy. Id. at 683. While there was no PSR information about purity in Baltazar, there is here: The PSR here included the DEA laboratory analysis of the 201.3 grams of a substance seized from one of Stowes co-conspirators and information about the conspiracy involving Stowe and Owens. Although the probation officer did not attribute that amount of methamphetamine to Owens, its purity nonetheless provides a reliable data point for determining the purity of the five pounds that were obtained from the same conspiracy and subsequently attributed to Owens. Owens cites our unpublished, nonbinding decision in United States v. Davalos-Cobian, 714 F. Appx 371 (5th Cir. 2017) (per curiam), but that case is also of no help to him. In that case, the PSR did not contain sufficiently reliable evidence tying the samples seized from a co-conspirator to the defendant because it was known that the co-conspirator had other suppliers aside from the defendant, the co-conspirator had issues converting the methamphetamine from the liquid form distributed by the defendant to the crystalline form seized from the co-conspirator, and the purities of past samples seized from the defendants co-conspirators varie[d] vastly. Id. at 374. By contrast, there is evidence here of a common supplier and no evidence of unreliable or inconsistent purity determinations. Accordingly, the district court plausibly inferred, by a preponderance of the evidence and in light of the record as a whole, that Owens was accountable for at least 1.5 kilograms of actual methamphetamine and thus properly sentenced him within the Guidelines to 324 months imprisonment. See Lucio, 985 F.3d at 485 (citation omitted); Sherrod, 964 F.2d at 1508; cf. Arayatanon, 980 F.3d at 452 ([O]n this record, the district court could plausibly infer, by a preponderance of evidence, that the methamphetamine was imported.). Because Owenss evidentiary argument is meritless, the district court would have adopted the same guideline range and imposed the same sentence even if the objection were made. Thus, Owens cannot show a reasonable probability that the result of the proceeding would have been different had his trial counsel objected at sentencing or his appellate counsel raised the argument on appeal. See Strickland, 466 U.S. at 694. Finally, Owens argues that the district court erred by resolving an evidentiary question without a hearing. We disagree. As the district court explained, [a] motion brought under § 2255can be denied without a hearing only if the motion, files, and records of the case conclusively show that the prisoner is entitled to no relief. See United States v. Bartholomew, 974 F.2d 39, 41 (5th Cir. 1992) (per curiam). In reviewing the record, the district court could properly rely on the PSR and Guidelines to apply the offense level determined by the weight of the pure methamphetamine as it resulted in a higher offense level. See Aparicio, 963 F.3d at 47475. Thus, the district court did not err in denying an evidentiary hearing. Accordingly, we AFFIRM the district courts denial of Owenss § 2255 motion. Jacques L. Wiener, Jr., Circuit Judge, dissenting: To sentence Jacob Ray Owens under the guidelines for possession with intent to distribute actual methamphetamine, the district court assumed that the drugs attributed to Owens had the same purity as those recovered from a separate coconspirator during a separate investigation. In affirming that courts denial of Owenss § 2255 motion, my colleagues hold that this inference was reasonable. I respectfully disagree. Instead, I would remand this case, either for an evidentiary hearing or for resentencing using the lower guidelines for conspiracy to possess with intent to distribute a mixture or substance containing methamphetamine. As the majority cogently lays out, the PSR concluded that Owens was responsible for at least 2.56 kilograms of actual methamphetamine: the 10.56 ounces recovered when he was arrested on November 5, 2019, and the five pounds that his co-conspirator, Brian Edward Stowe, says Owens helped him transport from Tijuana. Neither of these quantities were ever tested to determine their purity. Instead, the sentencing court relied on the testing of 205.5 grams of methamphetamine recovered from a confidential source working with Stowe, which was found to be 98% pure. The sentencing court thus inferred that the 2.56 kilograms attributed to Owens had a purity level that was identical to that of the methamphetamine seized from the confidential source because that methamphetamine came from Stowe, and Stowe and Owens were in the same trafficking conspiracy. Other circuits have noted that law enforcement is rarely able to recover all the methamphetamine a defendant is deemed responsible for at sentencing for the purposes of laboratory testing. United States v. Madison, 863 F.3d 1001, 1006 (8th Cir. 2017). As a result, a drugs source, price and appearance as well as statements or testimony by co-conspirators, users or dealers may constitute evidence of purity. United States v. Williams, 19 F.4th374,380(4thCir.2021).However, such evidence must be sufficiently reliable and specific. Id. The majority concludes that the following is sufficiently reliable evidence on which the district court could reasonably rely in charging Owens with 2.56 kilograms of actual methamphetamine: (1) Owens and Stowe were partners and, when he was in custody after being arrested with the 10.6 ounces, Owens placed multiple calls to Stowe to discuss their work and business; (2) Stowe sourced methamphetamine from Tijuana several times and made one trip to Tijuana with Owens where they purchased five pounds; and (3) some methamphetamine from Stowe was 98% pure. But, while a drugs source can be probative of purity, see Williams, 19 F.4th at 380, it is unclear whether the five pounds Stowe and Owens received came from the same supplier as the 205.5 grams later recovered from the confidential source. In fact, the PSR suggests that Stowe might have had multiple contacts for purchasing methamphetamine in Tijuana. It is not reasonable to infer that, simply because Owens worked with Stowe, the methamphetamine that Owens is charged with possessing must have been the same purity as the methamphetamine Stowe was separately involved in distributing, even if both quantities came from the same city. See United States v. Davalos-Cobian, 714 F. Appx 371, 373 (5th Cir. 2017) (per curiam) (holding that a PSR did not have sufficiently reliable evidence to connect the drugs in question to the defendant, as the middleman had other suppliers); cf. United States v. Rodriguez,666 F.3d944, 947(5thCir.2012)(determining that it was not clear error to infer that meth from the same supplier and sold at the same price had a similar purity level). My colleagues would surely agree that it is not reasonable to assume that all methamphetamine originating in Tijuana has the same purity. The PSR admittedly makes inconsistent use of the singular contact versus the plural contacts, even in the same sentence. The majority notes that the PSR elsewhere says, with no uncertainty, that Stowe utilizes an individual, and thus twice conveys that Stowe had only one supplier. But the PSR also says with no uncertainty that Stowe dealt with people in Mexico, which evens out the scorecard at 2-2. Because the reasonableness of holding Owens responsible for actual methamphetamine comes down to a finding that Stowe had only one supplier in Tijuana, and the PSRwaffles on this point, it was unreasonable for the district court to adopt and rely on the PSR without further evidentiary exploration. See U.S.S.G. § 6A1.3(a) (explaining that the information [in a PSRmust have] sufficient indicia of reliability to support its probable accuracy); see also United States v. Majors, Nos. 20-40405 & 20-40656, 2022 WL 301545, at *2 (5th Cir. Feb. 1, 2022) (quoting United States v. Cantu-Ramirez, 669 F.3d 619, 629 (5th Cir. 2012)) (finding PSRs to be lacking an adequate evidentiary basis because they were internally inconsistent).[3] I recognize that we must give deference to the district courts factual findings. United States v. Kearby, 943 F.3d 969, 974 (5th Cir. 2019). But these findings must be supported by a preponderance of the relevant and sufficiently reliable evidence. United States v. Aguilar-Alonzo, 944 F.3d 544, 549 (5thCir.2019)(emphasis added)(citation omitted).The PSR is not such evidence. Based on the information before that court, I respectfully cannot agree that it acted reasonably in finding Owens responsible for at least 2.56 kilograms of actual methamphetamine, as opposed to a mixture or substance containing methamphetamine. Because the guidelines for the two differ, had Owenss counsel objected to the courts purity determination, there is a reasonable probability that the result of the proceeding would have been different. See Strickland v. Washington, 466 U.S. 668, 694 (1984). I would therefore remand this case to the district court for (2) an evidentiary hearing or (2) resentencing based on the guidelines for conspiracy to possess with intent to distribute a mixture or substance containing methamphetamine
