[QUOTE="redneckdan, post: 1913787, member: 8932"] I have had a few loads with good statistics but poor grouping. Like others have said, seems to be due to barrel harmonics not matching bullet exit timing. Two recent examples are 6.5 staball with 115 dtacs and a standard federal primer in 6creed. 100yds group showed random impacts and couldn't get it below about an inch and a half. Started again with ramshot hunter, dtacs and wincheter magnums. Found a good load at about the same velocity in the high node that is grouping under 3/4" with SD of 6 for 10rds. [/QUOTE]
