I havent loaded an AMax into a gun that didnt like it, assuming that you keep within the bullet weight [read: LENGTH] vs. twist rate range.
I have loaded the 75 grain AMax in both a 1:7 twist AR (single shot...) and, believe it or not, into a 1:9 twist 527 CZ Kevlar Varmint. At 100 yards, it would hold around 1.5" for three shots. I was not impressed, as this was the best I could do trying all different combinations. However, at 300 yards, they actually tightened up, shooting about the same group. I think they took a bit to stabalize. I use the 52 grain AMax in a Sako .222 and a .223 (the Kevlar Varmint) and it shoots into a half inch pretty regularly, if I do my part.
My friend loads the 168 Amax into his Savage bull barreled 308. Im not sure of the load specifics, however it opens up a nickle sized ragged hole at 100 yards for 5 shots. He shot a deer with the same gun/load last season about about 60 or so yards here in Wetzel County, WV. Little hole in, destroyed the lungs, ribs, and heart, leaving a fist-sized exit leaving. They work well on game despite what Hornady tells you.
Try them, you wont be disappointed.
