[QUOTE="J E Custom, post: 1665406, member: 2736"] When I looked at the 6.5,s I chose the 260 rem AI for many reasons. I had plenty of good 7/08 and 308 cases (Lapua) and felt it would be the best way for me. I am a big fan of the Ackley,s and it seemed to be the right powder volume for a good 6.5 hunting round. With that said, I chose a 1 in 8 twist 3 grove barrel (For a little more velocity and longer throat life) I also chose a 24" Sendero contour. the action I chose was a Remington 788 because of the center feed feature. I did a traditional AI chamber using a 260 head space gauge so i could fire 260 ammo if need be. The rifle will stay just under 1/2 MOA while fire forming and in the fired cases 130 grain bullets will go beyond 3000 ft/sec and the 140, s are just under 3000 ft/sec. With the right load and barrel the AI will produce 100 to 150 ft/sec more velocity. The 788 Magazine will take a COAL of 2.815 with space to clear, so I load 2.815 and seat bullets that will allow some freebore. case density is at 95 to 98% with the best powders so I don't worry about compressed loads with the 140 grain bullets. In my opinion there are no downsides to the 260 AI and the fact that in a pinch you can use 260 Rem ammo that has equal or slightly better ballistics than the CM. and the fact that Lapua Now makes cases for it, I feel you are making a wise choice. Mine seems to realy like the 129 grain Accubond with the best 5 shot groups to date just under .200 thousandths and will realy send them fast and flat. Just my opinion on twist and Barrel length.
