I have a bunch of AI guns. At first, I was looking for magnum performance w/o the recoil/blast. That didn't happen. There are vel gains, but not 200 fps. I like them for the "cool" factor and that I don't have to trim the brass.

6mm Rem AI, 257 Roberts AI, 260 AI, 6.5-06 AI, 7x57AI, 280 AI, 30-06 AI, 30-30 AI, 375 H&H AI. I have 223 AI and 22-250 AI dies, just haven't gotten around to building the rifles yet.
