[QUOTE="Kevin Thomas, post: 373867, member: 15748"] Greywolf, My concern for this combo would be the potential for feeding issues, since the case configuration/shape of the AI family aren't exactly ideal for semi-auto feeding; some taper is a major advantage (even a requirement) there. As JE said, the combination you've described will work just fine for the 77s, and the 80s will work as long as you're single loading them. I'll have to part company on the 90s, though; they're not going to work in a 1x8" out of an AR platform. You'll need a 1x6"-1x6.5" for a sure thing, with a 1x7" being marginal in most situations. A 1x8" might work if we were looking at a 22-250 or similar case and a reasonably long barrel, but not out of an AR, or a 223 based case, improved or otherwise. As far as the added velocity from the Ackley Improvment goes, I think it was German Salazaar who once observed that "speed fades, but BC is forever." Smart guy, German!
