jj, you did not mentioned Caliber you intend to use. I would'nt take anythig less than .338MAG.

for Black's a .35REM and Brown,s a .300MAG, but Grizz's .338MAG.
This is my opinion. There are many hunters out there that will take them
with less, but have been shooting for years. I have taken Black's in Alberta with
Winchester 94 Carbine in .35 REM.
