in the 20"barrel of alloy framed,7 lb BAR,has plenty of penetration for use on bears, twice the repeat hit speed of 45-70 lever action, FAR more utility, by virtue of its 3x greater range, 1/3rd the price for practice ammo. The 180 gr sp will shoot thru over 2 ft of flesh, what you want, anyway? If you want more penetration, for use on fleeing cripples,just have the rest of the mag full of AP loads. They'll shoot thru a big Grizzly,end to end.
