[QUOTE="RockyMtnMT, post: 2409839, member: 7999"] I am not sure if I can say that we have been able to tell if one style of rifling is better than another. We have run a lot of 5 and 6 groove barrels but have never run a 3 groove. I would say the 5-6 are equal. The 3 groove has a reputation getting more speed but tough on jacketed bullets. We don't have jackets so no issue there. We have run an old 2 groove barreled 30-06 and it shot very well. So choosing from your listed barrels I would run the 10" twist 5 groove only for the extra stability. Not because of the number grooves. [/QUOTE]
