Tommy Merrel Jackson, federal prisoner # 27477-077, appeals the district court’s denial of his motion for grand jury materials, which was filed pursuant to Fed. R.CeimP. 6. The Government argues that the court lacked jurisdiction to consider Jackson’s motion because it is best construed as a successive 28 U.S.C. § 2255 motion. This argument is unavailing because the motion does not challenge Jackson’s conviction or sentence, nor does it seek 'to challenge the disposition of his first § 2255 motion. See 28 U.S.C. § 2255; Gonzalez v. Crosby, 545 U.S. 524, 532, 125 S.Ct. 2641, 162 L.Ed.2d 480 (2005).

Jackson’s argument that the district court erred by denying his request for grand jury materials is likewise unavailing. Jackson has not shown a particularized need for these materials. See United States v. Miramontez, 995 F.2d 56, 59 (5th Cir. 1993); In re McDermott & Co., Inc., 622 F.2d 166, 172 (5th Cir. 1980). Consequently, he has not shown that the district court abused its discretion by denying his motion. See Miramontez, 995 F.2d at 59. The judgment of the district court is AFFIRMED.
