RE: .284 Win / .308 Win / .300 WSM WHICH would you use for NY DEER HUNTING
IF I HAD a .284, I'd sure as hell use it. If not, the .308 with a 150-grain bullet would win hands down (of the choices you gave!!) Actually, I'd use a 7X57mm or a .45/70.......
The .284 is very close to the 7mm Rem. Mag., and is more rifle than the .308. But either are PLENTY for deer in a place where your shots will be under 400 yards-the .284 may be better than 400 yards, depending on how well your rifle shoots!!
Magnums are totally unecessary for any deer hunting!
