[QUOTE="jb1000br, post: 142267, member: 1459"] [b]Re: Let\'s talk copper fouling[/b] Most "gongs at 1000" are 2MOA + 1000yd BR groups need to be 1/2-1MOA to be competetive... Just depends on the precision you require... 60rds of 308 thru my broughton 5c = NO COPPER...but it is the carbon I worry about, not the copper... 60rds thru my 1KBR 6mmBR (also Broughton 5C) also = no copper...but the carbon has bit me before...
