So, I'm contemplating a 308 for hunting medium-larger size game. I have a couple AR15's and am impressed with their accuracy, versatility and modularity. But 223 is obviously not the best choice for larger game. Hence the allure with either an AR10 or FAL platform. Before caliber wars break out I'm dead set on 308. I have a bad shoulder and anything larger in 30 caliber is out of the question which would be flat enough and have energy at say 300 yards to take at least a deer. Having looked a bit I would lean toward the S&W M&P10 for the AR or a PTR in the FAL. Which platform (not make and/or model) do you prefer and why? Do you hunt with it? What game? How big of a projectile can I expect to reliably feed through either and shoot accurately? Since these platforms were designed to shoot 7.62 NATO 147 grain-ish projectiles, and I will want to load 200 grain+ projectiles should I expect to replace the barrel with a more suitable twist? Or would I be trying to do something that these military clones are simply not well suited for as opposed to a more traditional bolt action rifle? Thanks for your time.
