Before RILEY, BOWMAN, and HANSEN, Circuit Judges.
                           ___________

BOWMAN, Circuit Judge.

       A jury convicted Antwan Elvago Coplen on one count of conspiracy to
distribute cocaine powder and at least fifty grams of cocaine base (crack). The
District Court1 sentenced him to life in prison as a career offender. Coplen appeals the
conviction.

       After he filed his opening brief in this case, Coplen obtained new counsel. Her
reply brief on behalf of Coplen addresses the sufficiency-of-the-evidence issue raised

      1
      The Honorable Ronald E. Longstaff, United States District Judge for the
Southern District of Iowa.
in Coplen's opening brief and the concomitant arguments that the District Court erred
in denying Coplen's motion for judgment of acquittal or, in the alternative, a new trial.
But the reply brief also advances three new issues not raised in the opening brief.
According to Coplen, the District Court abused its discretion in admitting evidence
of a prior conviction, committed plain error in failing to give an accomplice-witness
instruction to the jury, and abused its discretion in denying Coplen's request for new
counsel. This Court ordinarily will not address issues raised for the first time in an
appellant's reply brief. United States v. Martinson, 

, 753 (8th Cir. 2005).
And to the extent the new claims challenge the effectiveness of Coplen's trial counsel,
those issues are best left for resolution by way of a motion for post-conviction relief
anyway. See 

for adjudication in this appeal only the sufficiency-of-
the-evidence issue and Coplen's corresponding objections to the denial of his motion
for judgment of acquittal or a new trial.2

         The basis for Coplen's post-verdict motion for judgment of acquittal or, in the
alternative, a new trial is his position, which he maintains in this Court, that the
evidence was insufficient to support a finding of guilt beyond a reasonable doubt. At
trial, the direct evidence of Coplen's drug-dealing was admitted through the testimony
of nine people who were involved, in one way or another, in the conspiracy charged.


      2
        On April 15, 2008, while this appeal was pending, Coplen filed in the District
Court a motion for a new trial based on newly discovered evidence. See Fed. R. Crim.
P. 33(b)(1). He then filed a motion in this Court for a limited remand so that the
District Court could dispose of the new-trial motion. We denied the motion for
remand on May 1, 2008, before this case was submitted on the merits on May 13,
2008. The District Court has now denied Coplen's motion for a new trial based on
newly discovered evidence. See United States v. Cronic, 

, 667 n.42
(1984) ("The District Court had jurisdiction to entertain the motion [while the appeal
was pending] and either deny the motion on its merits, or certify its intention to grant
the motion to the Court of Appeals, which could then entertain a motion to remand the
case."). Coplen has filed a notice of appeal from that decision, which has been
docketed separately from this appeal.

                                          -2-
Coplen asserts that the "evidence presented against [him] at trial was in the form of
testimony by incarcerated, interested witnesses, hoping to get sentence reductions,"
and there was no other evidence to corroborate that testimony. Br. of Appellant at 19.
But "[w]e have repeatedly upheld jury verdicts based solely on the testimony of co-
conspirators and cooperating witnesses." United States v. Coleman, 

,
666 (8th Cir. 2008). Although the witnesses who testified to Coplen's drug-dealing
did so with the hope (although not the promise) of reduced sentences, that did not
render the testimony inherently unreliable or require that it be corroborated in order
to be sufficient to sustain the conviction. See United States v. Baker, 

,
798 (8th Cir. 2004). The accomplice-witnesses testified at trial that they anticipated
reductions in their own criminal sentences in exchange for testifying against Coplen,
so the jurors were fully aware of the constraints under which the government's
witnesses may have testified and the possible motivation to perjure themselves.
Moreover, the testimony was not incredible on its face, and it is well established that
questions of credibility are otherwise for the jury to decide. See United States v.
McAtee, 

, 1104–05 (8th Cir. 2007). Here, the jury chose to credit
some—if not all—of the co-conspirators' testimony, as demonstrated by the verdict.

      Coplen argues that he was entitled to a post-verdict judgment of acquittal under
Rule 29 of the Federal Rules of Criminal Procedure. We review de novo the District
Court's denial of Coplen's motion for judgment of acquittal. See United States v.
Sturdivant, 

, 800 (8th Cir. 2008). We view the evidence in the light most
favorable to the government, resolve conflicting evidence in the government's favor,
and accept all reasonable inferences that may be drawn from the evidence where those
inferences support the verdict. 

the nine witnesses in question testified to
engaging in drug transactions with Coplen; the ninth testified that she witnessed
Coplen dealing drugs. If we view the evidence in the light most favorable to the
verdict, as we must, we conclude that a "rational trier of fact could have found the
essential elements of the crime beyond a reasonable doubt," notwithstanding Coplen's
objections to the unsavory character of some of the witnesses. Jackson v. Virginia,

                                          -3-


, 319 (1979). We cannot say that the District Court erred in denying
Coplen's motion for judgment of acquittal.

        Coplen contends that even if his motion for judgment of acquittal was properly
denied, he should have been granted a new trial. In ruling on a motion for a new trial
under Rule 33 of the Federal Rules of Criminal Procedure, unlike a Rule 29 motion
for judgment of acquittal, a district court has discretion to "weigh the evidence and
evaluate the credibility of the witnesses," but the court must allow the verdict to stand
unless a miscarriage of justice may have occurred. 

. The
District Court, in its order denying Coplen's post-verdict motion, noted that the
evidence of Coplen's guilt was "overwhelming." Order of July 18, 2007. But Coplen
claims that the verdict in this case is nevertheless a miscarriage of justice and a new
trial is required, again basing his argument on the credibility and character of the
witnesses who presented the bulk of the government's case against him. As we
explained above, the verdict is not called into question simply because of the nature
of the witnesses against Coplen. The District Court did not find a miscarriage of
justice, and we cannot say that the court abused its discretion in denying Coplen's
motion for a new trial. See 

(standard of review).

      The judgment of the District Court is affirmed.
