    UNITED STATES of America, Appellee, v. Tyler BROWN, Appellant.
    No. 10-1791.
    United States Court of Appeals, Eighth Circuit.
    Submitted: Oct. 7, 2010.
    Filed: Oct. 12, 2010.
    Before WOLLMAN, MELLOY, and GRUENDER, Circuit Judges.
   PER CURIAM.

A jury found Tyler Brown guilty of conspiring to distribute and possess with intent to distribute 50 grams or more of cocaine base, in violation of 21 U.S.C. §§ 841(a)(1) and 846, and the district court imposed the statutory mandatory minimum sentence of 120 months in prison. On appeal, defense counsel has moved to withdraw and has filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), arguing that the court should have sentenced Brown below the mandatory minimum using a one-to-one ratio of crack cocaine to powder cocaine to determine the drug penalty; the government violated Brady v. Maryland, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963), by waiting until the morning of trial to provide a witness’s rap sheet; and another witness gave false testimony before the grand jury. In pro se supplemental filings, Brown argues that counsel rendered ineffective assistance, the court should have sentenced him below the statutory minimum, and the court should have applied a November 2010 Guidelines amendment in calculating his criminal history score. We affirm.

Section 841 has been amended to raise the threshold for imposition of a 120-month minimum prison sentence, see Fair Sentencing Act of 2010, Pub. L. No. Ill— 220, § 2(a)(1), 124 Stat. 2372, 2372 (Aug. 3, 2010), but the amendment was not made retroactive, see United States v. Carradine, 621 F.3d 575, 579-81 (6th Cir.2010) (general savings statute, 1 U.S.C. § 109, requires application of penalties in place at time crime was committed unless new enactment expressly provides for its own retroactive application; Fair Sentencing Act of 2010 contains no express statement that it is retroactive and no such express intent can be inferred from its plain language). Thus the statutory minimum existing at the time the offense was committed governs.

We also find no Brady violation, much less a reversible one, see United States v. Greatwalker, 356 F.3d 908, 911-12 (8th Cir.2004) (per curiam), and any perjured testimony before the grand jury was rendered harmless by the petit jury’s guilty verdict, see United States v. Wilson, 565 F.3d 1059, 1070 (8th Cir.2009), cert. denied, — U.S. -, 130 S.Ct. 1052, — L.Ed.2d - (2010). As to the ineffective-assistance claims, these matters are not properly raised in this direct criminal appeal, see United States v. Ramirez-Hernandez, 449 F.3d 824, 826-27 (8th Cir.2006); and Brown was not entitled to the benefit of a Guidelines amendment that was not in effect at his sentencing (which would not have helped him anyhow in light of the mandatory minimum). Finally, having conducted our review under Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we find no nonfrivo-lous issues. Accordingly, we grant counsel’s motion to withdraw, and we affirm the district court’s judgment. 
      
      . The Honorable Lawrence L. Piersol, United States District Judge for the District of South Dakota.
