Federal inmate Jerome Perry Hearne appeals the district court’s 1 order dismissing his 28 U.S.C. § 2241 petition. The district court found Hearne’s inability to file a successive 28 U.S.C. § 2255 motion did not make section 2255 inadequate or ineffective to test the legality of his sentence, and we agree. See Hill v. Morrison, 349 F.3d 1089, 1091 (8th Cir. 2003) (prisoner has burden of demonstrating § 2255 relief in the sentencing court would be inadequate or ineffective; § 2241 relief *929 is not available merely because prisoner faces substantive or procedural barrier to § 2255 relief). Accordingly, we affirm the judgment of the district court. See 8th Cir. R. 47B. We deny as moot Hearne’s motion for an expedited ruling.
