[QUOTE="J E Custom, post: 469167, member: 2736"] It is a fun little round and very accurate. You will have to change the bolt face from .473 to .378 and the easy way is to buy a new bolt from PT&G (I would get it with the M16 style extractor). Another thing that is nice about is that It will shoot 223 ammo with amazing accuracy so you can hunt with your favorite ammo in 223 and fire form at the same time. once you fire form enough brass you can start reloading the AI for an additional 100 to 150 ft/sec. The AI has about 8% more case capacity and brass last almost indefinitely, especially if you buy some of the Lapua brass. I built mine on 23" #7 contour 1 in 8 twist Lilja to shoot up to 70 grain bullets. It shoot 1/4 MOA with 223 fir forming loads and under 1/10 MOA with the AI loads. There is lots of loading data on Graymist .223 AI loading page in 6mm BR. J E CUSTOM [/QUOTE]
