[QUOTE="J E Custom, post: 1762102, member: 2736"] I see this often when using fast twist barrels. That is the reason I went with the 1 in 15 and 1 in 16. I also had the same problem with the 7mm I talked about at 3800 ft/sec. It had a 1 in 9.250 twist and Just over 3800 ft/sec all accuracy went away because of jacket shedding. I also saw this with some 223's that had a 1 in 7 twist. I backed off on my 223 AI and used a 1 in 8 twist and this thing will out shoot me every time Not to hard But with group size hovering just under .200 thousandths, it is very consistent. Some of the guys that I know that shoot matches had went to 1 in 7 to shoot the heavier bullets and went back to 1 in 8 after a while. In my opinion, You can go to far with fast twist and may only find one bullet that will work. J E CUSTOM [/QUOTE]
