Depends on what you intend to hunt with it. It won't do for really small animals but is great for medium to large game.
Deer require a rifle and shooter to be able to shoot about 3 MOA for a maximum range of around 330 yds. In other words you need to be able to keep your rounds inside a 10 inch circle/vital zone in order to get a clean kill. If you had a rifle in .308 Win that you could shoot 2 MOA consistently it would be good for 500 yds. on deer. You also need to have about 1000 ft. lbs of energy at the targets distance to get that clean kill. The .308 Win. will do this with the proper bullet at 500 yds, so long as you do your part. The M1A is a decent hunting rifle.
History is a freak show and a dark comedy. Mankind is a spectacle all to itself. Play your role, let the jesters play theirs. In the end...who has the last laugh?
