Sydney Kirkland Dudley, Sr., federal prisoner # 05789-051, appeals the district court’s dismissal of his 28 U.S.C. § 2241 habeas corpus petition, which challenged, inter alia, his conviction for engaging in a continuing criminal enterprise (“CCE”) in violation of 21 U.S.C. § 848. Dudley argues that his CCE conviction was invalid under Richardson v. United States, 526 U.S. 813, 119 S.Ct. 1707, 143 L.Ed.2d 985 (1999), and that, if 28 U.S.C. § 2241 relief is not available, the district court should have recharacterized his petition as a 28 U.S.C. § 2255 motion and transferred the motion to the sentencing court in the Western District of Texas. His remaining arguments have been abandoned on appeal. See Cinel v. Connick, 15 F.3d 1338, 1345 (5th Cir. 1994); Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993).

Although Dudley could proceed under 28 U.S.C. § 2241 if he demonstrated that 28 U.S.C. § 2255 relief was “inadequate or ineffective” under the latter statute’s “savings clause,” he has failed to make such a showing. See Reyes-Requena v. United States, 243 F.3d 893, 904 (5th Cir. 2001); Jeffers v. Chandler, 253 F.3d 827, 829-31 (5th Cir. 2001). Moreover, as Dudley advised the district court that he had previously filed a 28 U.S.C. § 2255 motion, the district court did not abuse its discretion by declining to transfer Dudley’s case to the Western District of Texas. See 28 U.S.C. §§ 1404, 1406; Caldwell v. Palmetto State Sav. Bank, 811 F.2d 916, 919 (5th Cir. 1987); 28 U.S.C. §§ 2244(b)(3)(A), 2255.

AFFIRMED.
