Appellant Jeffrey Acklen (Acklen) appeals the district court’s denial of his petition for *741 relief under 28 U.S.C. § 2255. We vacate and remand.
Facts and Proceedings Below
On January 25, 1990, a federal grand jury returned a twelve-count indictment charging Acklen with a variety of drug-trafficking offenses for which Acklen acted primarily as financier. In March 1990, the government agreed to dismiss the indictment in exchange for Acklen’s plea of guilty to a bill of information. The superseding information charged Acklen in count one with conspiracy, from March through December 1989, to manufacture and distribute methamphetamine, a Schedule II controlled substance, 1 in violation of 21 U.S.C. §§ 846, 841(a)(1) and in count two with distribution of methamphetamine in September 1989 in violation of 21 U.S.C. § 841(a)(1). As part of the plea agreement, Acklen stipulated that the amount of methamphetamine produced as a result of the conspiracy was at least ten but less than thirty kilograms. The district court accepted the plea, entered a judgment of guilty, and, consistent with the plea agreement and Presentence Investigation Report (PSI), on July 9, 1990, sentenced Acklen to two concurrent twenty-year terms of imprisonment and six years’ supervised release. 2 Acklen’s conviction and sentence were affirmed on direct appeal in an unpublished opinion issued by this Court on May 15,1991.
Thereafter, on June 21, 1993, Acklen filed the instant motion under 28 U.S.C. § 2255 to set aside, vacate, or correct his sentence, urging that his trial counsel’s failure to contend at sentencing that the methamрhetamine involved was 1-methamphetamine and not d-methamphetamine rendered his representation constitutionally ineffective. Acklen also requested discovery of alleged exculpatory material, a lab report, which Acklen contends would conclusively estаblish the type of methamphetamine involved in this case. 3 The district court refused to permit discovery and denied the section 2255 motion, but granted Acklen’s motion for leave to proceed in forma pauperis on appeal.
Discussion
Relief under 28 U.S.C. § 2255 is reserved for transgressions of constitutional rights and for a narrow range of injuries thаt could not have been raised on direct appeal and would, if condoned, result in a complete miscarriage of justice.
United States v. Segler,
Acklen’s constitutional claims in this case center around the assumption that 1-methamphetamine, and not d-methamphetamine, wаs the drug involved in this case.
4
D- and 1-methamphetamine are stereoisomers of methamphetamine; they consist of identical molecules differently arranged.
See generally United States v. Bogusz,
Essentially, Acklen argues that his attorney was ineffective for failing to object at sentencing to the assumption that the methamphetamine involved in this casе was d-methamphetamine and not 1-metham-phetamine. Absent • unusual circumstances not shown to be present here, establishment of ineffective assistance of counsel satisfies cause and prejudice.
United States v. Patten,
As to prejudice, Acklen alleged that, had counsel objected tо the assumption that the drug involved was d- as opposed to 1-meth-amphetamine, his sentence would have been far less severe. The basis for Acklen’s allegation that the methamphetamine involved was in fact 1-methamphetamine is wholly unclear; apparently, this allegatiоn is nothing more than an inference drawn from the government’s failure to produce a lab report, a report which Acklen has never seen but presumes can “conclusively” determine the type of methamphetamine involved. 6 Recognizing *743 that “petitioner was indeed prejudiced if the substance involved was L-methamphetamine,” thе district court assumed “that the substance involved in this crime was indeed L-methamphetamine.” Nevertheless, the court concluded that Acklen had failed to demonstrate that his trial counsel had acted unreasonably.
Unlike the district court, we are not convinced that this record demоnstrates as a matter of law that Acklen’s trial counsel’s performance in this case was not deficient. Although, at the time of sentencing, there was very little case law on the distinctions between d- and l-methamphetamine, the commentary to section 2D1.1 of the Sentencing Guidelines еxplicitly distinguishes 1-methamphetamine from other isomers — a distinction upon which turns a remarkable difference in sentencing liability.
See United States v. Lande,
Because we cannot say that this record demonstrates as a matter of law that counsel acted reasonably in this case,
8
we must consider whether Acklen has established prejudice, something the district cоurt assumed
arguendo.
We agree with the district court that prejudice occurred
if,
as Acklen alleges, the drug involved was actually l-methamphetamine.
9
However, we do not regard Acklen’s mere conclusory allegation that “conclusive evidence” exists that the methamphetamine was 1 (see note 6,
supra),
as being sufficient to establish that, or put in genuine issue whether, the substance was 1-methamphetamine, absent which no prejudice would be shown.

Conclusion
The judgment of the district cоurt is VACATED and the cause is REMANDED.
Notes
. See 21 U.S.C. § 812(c) (defining as a Schedule II drug "any injectable liquid which contains any quantity of methamphetamine, including its salts, isomers, and salts of isomers”).
. Notwithstanding the government’s suggestions to the contrary, the parties to the plea bargain did not agree to a specific sentence. The agreement reads, "Defendant acknowledges that sentencing in this matter is within the discretion of the Court, and that on each count he faces a maximum penalty of twenty (20) years imprisonment, or a fine of not more than $1,000,000.00, or both....” Although the sentencing range calculated under the Guidеlines was 262 to 327 months, the PSI noted that, under the statute, the maximum term of imprisonment on both counts was 20 years. At sentencing, the court remarked, “Your plea bargain states that you will be sentenced to no more than twenty years. The sentence is twenty years on both counts to run concurrently." On direсt appeal, this Court stated: "Under the plea agreement, ... Acklen's maximum penalty was twenty years imprisonment and six years supervised release.”
In stating the maximum term of imprisonment, the plea agreement, implicitly, and the PSI, explicitly, relied on section 841(b)(1)(C). Given the stipulated quantity of mеthamphetamine, however, the appropriate provision may be section 841(b)(1)(A). Under section 841(b)(1)(A), an offense involving “1 kilogram or more of a mixture or substance containing a detectable amount of methamphetamine, its salts, isomers, or salts of its isomers” requires a sentenсe no less than 10 years and no more than life. Thus, unlike section 841(b)(1)(C), which involves far smaller amounts of methamphetamine, section 841(b)(1)(A) does not provide a maximum term of imprisonment besides life. Neither of the parties raises any issue in respect to this possible discrepancy.
.In an Octоber 1993 motion for extension of time to file a traverse to the government’s response to the petition, Acklen also indicated that he wished to pursue a
Brady v. Maryland,
. To the extent Acklen’s motion is grounded on the government’s failure to prove, and the district court's failure to find, at sentencing, that the substance involved was actually d-methamphetamine, the absence of an objection at sentencing or on apрeal operates as a procedural bar.
See United States v. Deninno,
. This reference to 1-methamphetamine appears only in the Drug Equivalency Tables in the commentary to section 2D 1.1. In contrast, the Drug Quantity Tables, under section 2D 1.1(c), refer only to "methamphetamine” and "methamphetamine (actual),” which means d-methamphetamine (or possibly dl-mеthamphetamine, a matter we do not here determine).
See Bogusz,
.Acklen allegеd that "[h]ad petitioner's counsel conducted a proper investigation, he would have found that there was conclusive evidence available that the 'methamphetamine' involved was Levo — as opposed to Dextro — methamphetamine, and petitioner would have received a substantially lower term of imprisonment.” There is no statement of what the "conclusive evidence” is or how Acklen knows of it or any indication of any basis for his belief as to the character of the methamphetamine.
*743 Acklen’s brief on this appeal asserts in sеveral places that at the time of trial and sentencing he "had no idea of what type of ‘Methamphetamine’ was actually involved” and "is not personally knowledgeable of the process for making any type of methamphetamine.” We find no support in the record fоr the district court's statement in its ruling denying section 2255 relief that Acklen asserted "that he informed his attorney of the discrepancy in the drug types with which he was charged," and that "he repeatedly requested his attorney to explore this issue.” Acklen alleged that at his sentencing he was unaware that the Guidelines treated different types of methamphetamine differently. Acklen’s brief in the present appeal does assert that "[i]n the street vernacular, most people refer to” d-methamphetamine “as simply ‘methamphetamine.’ ”
As reflected in our direct appeal opinion, "[a]t sentencing, Acklen objected to the PSIR. First, he argued that the PSIR did not report that he was a drug addict and dependent on methamphetamine. According to Acklen, this addiction allowed Horace Ashley, a co-conspirator, to coax Acklen into thе conspiracy [to manufacture and distribute methamphetamine].” This would seem to suggest that d-methamphetamine was involved as l-methamphetamine "produces little or no physiological effect when ingested." Bo-gusz-
.The first reference to this issue in a published opinion of this Court appears to be in
United States v. Evans,
. Of course, a more complete record might reflect that counsel did adequately investigate or the like.
. Had the standards for l-methamphetamine been applied, Acklen’s sentence would have ranged from 108 to 135 months, as opposed to the 240 month sentence imposed and the 262-327 month range calculated in the PSI. The 1-methamphetamine sentence is thus significantly less harsh.
See Spriggs,
. With respect to his
Brady
arid p'erjury claims, Acklen has likewise failed to substantiate his allegation that the lab report retained by the government contained any reference to the type of methamphetamine and, even if it did, that the identified isomer was l-methamphetamine. It is plausiblе that any lab report on the substance seized in this case merely identifies the drug as methamphetamine without specifying the isomer type,
see United States v. Carroll,
. And, mere absence of the lab report does not suffice for this purpose.
