I have a savage in .243 I shoot the 80g ttsx out of it (I have to shoot lead free) 1.5" at 100 yards is as good as it gets . this is not good ! the barrel twist is 1 in 9.5 I'm looking to rebarrel it should I go to 1 in 8 . I have some emails out to a few barrel makers but holidays making it slow . and I would like to see what some of you guys say before I get the wrong twist and this thing gets worse . I have done ladder loads short and fast -short and slow and long and fast - long and slow and every thing in-between I have tried nosler's no luck tame results so after 200 round I went and stayed with Barnes ttsx did a ladder set 200 rounds powder and col nothing better than 1.5 in worst was 3" 3 shoot group
