OPINION
George Hopkins seeks relief pursuant to 28 U.S.C § 2255 based upon a claim that his trial counsel was ineffective by asserting that the sentencing judge lacked the authority to run his federal sentence concurrent with a yet-to-be-imposed state sentence. He asserts that the Supreme Court’s decision in Setser v. United States, -U.S.-, 132 S.Ct. 1463, 182 L.Ed.2d 455 (2012), demonstrates that such authority existed and that he is entitled to relief. Focusing as we must on the law as it existed at the time of sentencing, we conclude that defense counsel was not ineffective and we will affirm.
I
As we write principally for the benefit of the parties, we recite only the essential facts and procedural history. In the summer of 2005, Hopkins was serving a sentence at the Dauphin County Work Release Center. At some point, he left the facility and did not return as required. A few months later, Hopkins and a friend drove to the Center to retrieve Hopkins’s personal belongings. The friend went inside while Hopkins waited in the car.
A probation officer saw Hopkins sitting in the car and approached him. Hopkins pulled out a .22 caliber pistol and shot at the officer, grazing him in the back. Officers arrested Hopkins and took him to the Dauphin County Prison. During a routine search, prison officials found 8.6 grams of crack cocaine in Hopkins’s underwear. *145Hopkins was thereafter charged with federal and state offenses.
On the federal side, a grand jury returned a two-count indictment charging Hopkins with possession with intent to distribute five grams or more of crack cocaine, in violation of 21 U.S.C. § 841(a)(1), and being a felon in possession of a firearm, in violation of 18 U.S.C. § 922(g)(1). Hopkins pled guilty to the drug count and the firearms charge was dismissed.
On the state side, a Pennsylvania jury convicted Hopkins of two counts of aggravated assault upon the probation officer, carrying a firearm without a license, possession of a firearm by a felon, recklessly endangering another person, and providing false identification to police.
The District Court imposed its sentence first. During the sentencing hearing, Hopkins’s attorney noted that Hopkins would be sentenced in state court in the future but never argued that the federal sentence should run concurrent with the future state sentence. To the contrary, defense counsel asserted that the sentences must run consecutively. JA 55-56 (“Because we’re proceeding with sentencing prior to any disposition in terms of sentence in state court, he’s a state prisoner, he can’t get any concurrent sentence despite what the presentence report indicates.”)
The District Court sentenced Hopkins to 188 months’ imprisonment but made no statements regarding whether the sentence should run concurrent with or consecutive to the yet-to-be imposed state sentence. Several weeks later, the state court imposed an aggregate sentence of 150 to 360 months’ imprisonment and ordered that the state sentence run consecutive to the federal sentence.
Hopkins’s federal sentence was based on his designation as a career offender, but this designation was vacated in light of Chambers v. United States, 555 U.S. 122, 129 S.Ct. 687, 172 L.Ed.2d 484 (2009). Hopkins v. United States, 555 U.S. 1132, 129 S.Ct. 995, 173 L.Ed.2d 285 (2009). On remand, we held that Hopkins was not a career offender, but that “[t]his conclusion [did] not require any change in Hopkins’[s] sentence” because Hopkins’s assault on the officer triggered application of the official victim enhancement, which resulted in the same sentence. United States v. Hopkins, 577 F.3d 507, 515 (3d Cir.2009). We therefore affirmed the sentence. Id. Hopkins’s sentence was later reduced to 92 months’ imprisonment due to the amendments to the Sentencing Guidelines relating to crack cocaine offenses.
Hopkins thereafter filed a motion pursuant to § 2255, claiming, among other things, that his counsel was ineffective under Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984), for failing to request a concurrent sentence. Hopkins sought to amend his motion to assert that he is entitled to resen-tencing under Setser v. United States, — U.S.-, 132 S.Ct. 1463, 182 L.Ed.2d 455 (2012), which he contends simply restates existing law that gave sentencing judges the discretion to order that their sentences run concurrent with or consecutive to a yet-to-be imposed sentence.
The District Court found that because “Setser had not yet been decided and [Hopkins’s] counsel did not believe that his federal sentence could be imposed concurrently with his state sentence,” the ineffective assistance claim was meritless. JA 12. The District Court also denied the request to amend the motion based upon Setser because it concluded that Setser announced a new rule of law that did not apply retroactively under Teague v. Lane, 489 U.S. 288, 306, 109 S.Ct. 1060, 103 L.Ed.2d 334 (1989), and therefore could *146not provide Hopkins a basis for relief. The District Court granted certificates of appealability on both issues. For the reasons set forth, we will affirm.

In Strickland, the Supreme Court provided the standard for judging ineffective assistance of counsel claims. 466 U.S. at 687, 104 S.Ct. 2052. To succeed on his claim, Hopkins must show “(1) that his counsel’s performance was deficient; and (2) that he was prejudiced by it.” United States v. Lilly, 536 F.3d 190, 195 (3d Cir.2008).
We first address whether Hopkins has shown “that his counsel’s representation ‘fell below an objective standard of reasonableness.’ ” Id. at 196 (quoting Strickland, 466 U.S. at 688, 104 S.Ct. 2052). “A court ‘deciding an actual ineffectiveness claim must judge the reasonableness of counsel’s challenged conduct on the facts of the particular case, viewed as of the time of counsel’s conduct.’ ” United States v. Davies, 394 F.3d 182, 189 (3d Cir.2005) (quoting Strickland, 466 U.S. at 690, 104 S.Ct. 2052, and adding emphasis).
To determine whether Hopkins’s counsel was ineffective at sentencing, we must assess the state of the law at the time of Hopkins’s sentencing with respect to a federal court’s authority to impose a sentence to run concurrent with the yet to be imposed state sentence. Davies, 394 F.3d at 189. At the time of sentencing, this Court had made statements on this subject only in eases that predated the Sentencing Reform Act. In United States ex rel. Lester v. Parker, 404 F.2d 40, 41 (3d Cir.1968) (per curiam), this Court held that a federal sentence ordered to run consecutive to a future state sentence was sufficiently definite to satisfy due process. Thus, Lester provided authority for a sentencing court to impose a sentence to run consecutive to a future sentence.2 Id. at 42.
The language used in the then-existing precedent addressing the authority of a federal sentencing judge to order the federal sentence to run concurrent with a yet-to-be-imposed state sentence was different. For instance, in Barden v. Keohane, 921 F.2d 476 (3d Cir.1990), this Court, in holding that only the Bureau of Prisons had the authority to decide whether a state prison should be designated as the defendant’s place of federal confinement, and thereby allow the federal sentence to be served concurrent with the state sentence, specifically stated (without explanation) that the district court was “powerless” to order that a sentence run concurrent with a future sentence. Id. at 483. Barden relied upon Gomori v. Arnold, 533 F.2d 871 (3d Cir.1976), in which this Court also stated (again without explanation) that a “federal court has no power to direct that a federal sentence shall run concurrently with a state sentence,” and that it only had the ability to “recommend to the Attorney General that he designate a state institution as the place of service of a federal sentence in order to make it concurrent with a state sentence being served at that institution.” Id. at 875.
*147While each of these cases involved review of the statutory authority that vested the Attorney General with the discretion to designate a state institution as the place at which a federal sentence could be served, this Court as well as at least one other relied on this statutory authority to say that a district court was powerless to order that its sentence run concurrent to or consecutive with a future sentence. Setser, 132 S.Ct. at 1468 n. 2. Although some of this statutory authority had been repealed by the time Hopkins was sentenced, and even though none of the eases addressed the authority granted under the Sentencing Reform Act, the language in this precedent was unequivocal and counsel reasonably relied on it. Furthermore, as a result of this strong language, it was also reasonable for defense counsel not to bring to the sentencing court’s attention cases from other circuits that had held there was authority to impose a federal sentence to run concurrent with a yet to be imposed state sentence. Cf. Jansen v. United States, 369 F.3d 237, 243-44 (3d Cir.2004) (counsel’s performance deficient where he failed to cite favorable out of circuit cases that were readily available). Thus, counsel’s performance was not deficient.3
*148Even if counsel’s failure to advocate for a concurrent sentence was ineffective, Hopkins has not shown prejudice, that is, that “there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Strickland, 466 U.S. at 694, 104 S.Ct. 2052. In the sentencing context, Hopkins must show there was a reasonable probability that “the deficient performance affected [his] sentence.” United States v. Hankerson, 496 F.3d 303, 310 (3d Cir.2007) (citing Glover v. United States, 531 U.S. 198, 203-04, 121 S.Ct. 696, 148 L.Ed.2d 604 (2001)). A “totally speculative” harm, Baker v. Barbo, 177 F.3d 149, 154 (3d Cir.1999), or the “mere possibility” of receiving a concurrent sentence, see Prewitt v. United States, 83 F.3d 812, 818-19 (7th Cir.1996), does not demonstrate prejudice.
Here, we cannot say that there exists a “reasonable probability” that the District Court would have imposed a concurrent sentence even if counsel had asked for it. Strickland, 466 U.S. at 694, 104 S.Ct. 2052. While the violent nature of the conduct underlying the state offenses enhanced Hopkins’s federal sentence, the state and the federal convictions were for entirely different crimes. The state convictions related to the shooting and Hopkins’s possession of the firearm, whereas the federal conviction related only to the crack cocaine. Because it is likely that a federal sentencing court would have wanted to ensure that Hopkins was separately punished for these separate offenses, it is likely that the court would have ordered its sentence to run consecutive to the future state sentence.
Moreover, a sentencing court would likely have found a consecutive sentence appropriate here in light of the nature of Hopkins’s conduct and criminal history. As the sentencing court noted, Hopkins’s crimes were violent, he had previously escaped from the Work Release Center, he had been undeterred by previous punishments, and he presented a serious risk of recidivism. Thus, Hopkins would have likely received a consecutive sentence even without counsel’s alleged error and he cannot show that he was prejudiced by his counsel’s failure to request a concurrent sentence.

For all of these reasons, we will affirm.
