I don't know what the twist rate would be like in that rifle, but you are going to need a fast twist to stabilize those bullets as they are a long bullet. I think that perhaps you may be referring to 75 grain A-max's unless Hornady is now making a V-max in that weight. I have loaded the 75 A-max bullets in 5.56, but you have to seat them pretty deep and apply a good crimp to keep them where they are supposed to be, but they seem to really shoot well out of a 1 in 7" twist barrel. They also expand very, very well and would probably work on small game (perhaps even deer - dare I say). It would also help to drive them as fast as possible.
