Home Forums Hunting & Shooting Ask The Gunwriters Mule Deer- Know of any .270 brown/grizzly kills?

A younger brother has killed two Alberta grizzlies with a .270 Winchester with ammo I loaded for him. Winchester cases, Winchester primers, 54 grains of IMR4350, and 130 grain Hornady SP. This was some years ago so it may have been before the InterLock was introduced.
