Shawn M. Ross appeals the 70-month prison sentence the district court 1 imposed after he pleaded guilty to attempting to manufacture at least 35 grams but less than 50 grams of actual methamphetamine, in violation of 21 U.S.C. §§ 841(a)(1), (b)(1)(B), and 846. On appeal, Ross’s counsel has moved to withdraw and has filed a brief pursuant to Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), arguing that Ross was denied effective assistance of counsel.

We adhere to the general rule that Ross must raise his claims of ineffective assistance of counsel in a 28 U.S.C. § 2255 proceeding, where the record can be properly developed. See United States v. Hughes, 330 F.3d 1068, 1069 (8th Cir. 2003). After reviewing the record independently under Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), and finding no non-frivolous issues, we affirm the judgment of the district court and grant counsel's motion to withdraw on condition that counsel inform appellant about the procedures for filing petitions for rehearing and for certiorari.
