One can get "fancy", or just use what works. My son and I took bull caribou this year using the same Wallyworld special Rem 770 (yeah, I know!) in 30-06, both over 300 yards, using 150 gr Corelokt factory ammo. And a Tasco scope.....
. The rifle a virgin no more...
My wife took her bull using a short barreled, tang RU77, also in '06, at 200 yards, Hornady reduced recoil ammo.
