When horse packing in Grizzly country (MT's Bob Marshall) I carry a 5" 629 Classic loaded with 285 grain Hard Cast bullets that I handload to about 1200 fps. When I'm living in a tent in Black Bear country (NE Oregon) I use the same 629 but with 240 grain Hollow Points. I expect the Grizzly that I see in MT to be twice the size of the Black I see in Oregon. Big difference.
