I have a buddy who doesn't reload and he only shoots Winchester white box 240gr SP out of his 4" performance center 629. I was skeptical when I first met him but he's killed a handful of black bears and one charging 8' grizzly with one shot apiece. And the grizzly was not a head shot, center of the chest at 10 yards folded him up like a cheap lawn chair. Pretty hard to argue with that.

The various 180 and 240 grain Remington loads seem much softer than either the HP or SP 240 from Winchester.
