[QUOTE="Coyoter, post: 21859, member: 236"] A few other thoughts: Have you tried weighing your cases? With your new batch of cases the variance between lots of your once fired brass should be minimized, but it's worth a try to find the best matched cases and see if the inconsistancy continues. When you say "deburring" I hope you mean the flash holes... Are you using Bench Primers? The differance with RL-22 and Fed 215, CCI 350s, CCI 250s and CCI BR-2s has made a major differance in group size and standard deviation in my experience. With the BR-2s at the top of the heap with that particular powder as well as with Varget. Gold Medal match primers may be another viable option depending on your favorite powders. Your barrel is free floated isn't it? Action bedded? Good shooting, Coyoter [ 02-11-2002: Message edited by: Coyoter ] [/QUOTE]
