I've shot jackrabbits with the 458 Winchester

Good going. I've shot grouse with my "long throated" .458 2". 510 WW at 2,060fps, and a red squirrel with my .69 - 482gr. RB.
Shot lots of grouse with the .69 and round ball loads while moose hunting. Always seem to have 165gr. of 2F loaded when I get a good shot at a grouse's head. Instant kills!
