On the whitetail buck I shot at 200 the 170 Silvertip went through him broadside and exited for a quick kill. The moose I had to follow into the thick stuff due to a lesss than optimal hit I put on him with a .30-06. I exchanged for my open sight 30/30 to follow him into the thicket. I found him at ten yards and he came to his feet and I sent two 170 Silvertips into his heart which put him back down and killed him. Both Silvertips were in his heart and they had mushroomed perfectly. Those shots were only ten yards which explains the lack of penetration.
