[QUOTE="SaskShooter, post: 647258, member: 42520"] A while back I bought a brick of CCI 30 grain TNT ammo in .22 WMR, it was cheap and VERY fast, but after the first box I noticed that it had an AWFUL fouling issue! I cleaned the barrel, squeaky-clean and fired one 3 shot group at 50 yards- CTC it was .75''- decent. So I fired another- CTC 1.4'', and so on and so forth. Every group I shot widened out until it hit 2.5'' and then it hovered around that. I cleaned it again, and shot another group around .65'' but then it widened out again over the next groups! I had a suspicion, so I finally cleaned it out and fired ONE shot, pointed the muzzle down over a white sheet of paper, and tapped the buttplate- unburnt powder spilled out onto the paper. Looking down the bore with the bolt removed it looked like someone had poured sand down the barrel. Now here's the really weird part, IF I swab the bore every shot like a muzzleloader the CCI ammo will shoot groups of less than .20'' CTC at 50 yards! My gun isn't very picky about ammo, and it's fairly normal to find a few grains of unburnt powder left in the bore after a shot with any ammo in this gun, but what happened with the CCI stuff was unacceptable. So, has anyone else seen this problem with their CCI ammunition, or is this some bizarre fluke? [/QUOTE]
