But other Silvertips have definitely come apart, even on much lighter bone. I once shot a 150-grain .30-06 Silvertip factory load into the shoulder of a forkhorn mule deer at 200 yards, and the bullet didn't even penetrate the rib cage. I found what was left of the empty jacket inside the broken shoulder, after I'd tracked the wounded deer down and shot it again through the ribs (which worked fine). My late friend Walter White had a terrible time with a huge brown bear up on Kodiak Island. Walter used 300-grain Silvertips in his .375 H&H;, and shot the bear at least 11 times (he picked up that many empties), and had to reload the magazine in his Model 70 Winchester twice. The bullets were breaking up on the wet hair and hide of the bear. I've also seen 180-grain Silvertips from the .30-06 come apart on elk shoulders.
