Not yet, been afew times but I think the deer are scared of them. I have shot several deer with the rifle tripple shock version a 10pt the bullet broke both front leg bones passing through heart, deer plowed ground about 10yds, doe I gut shot at 200yds didnt allow for cross wind she went 20yd and fell, she was dead in less than 3 minutes. those pedals are razor sharp. I have never seen a gut shot deer die that fast. They will pentrate a deer from end to end, in the south in thick pine plantations a exit wound is a must for me, it takes a lot of blood to trail a deer in pine straw a drop falls through the needles to ground were you cant see it, only marking the needle in a very small spot the needles are very thin. And its to thick to just walk around and hope to see the deer. With other ML bullets I have had pentration problems, a bullet that doesnt make it out the other side is a failure to me. Hunting from tree stands my entry hole is high a lot of times making the exit very nessary. I'll update when I get one.
