The only really big game I've shot with Sierras were moose; and they seemed to die in the approved fashion. The 130 grain flat-base 270 through the ribs, tipped them over like a big deer. I've also used the 215 Pro-hunter in the .338 Win. How well that one works depends on whether you go by the results or what the bullet looks like when its over. The they seem to like to slip their jackets right about the time they stop moving forward; with the jacket and core either right together or easily pulled apart with your fingers and about 1/2 their weight shed if you don't count the loose jacket. On the other hand; the moose tended to be dead so all is not lost. Frankly, they wouldn't be my first choice but a friend is quite happy shooting grizzlies and everything else in BC with them.
