Yes, the deer was a mule deer where we found bullet pieces in the grinder. That was a very sharp raking shot that entered the left shoulder and the bullet went all the way into the left hip, breaking up the whole way through. I had one bullet not penetrate completely through on a 150 pound mule deer at about 300 yards. The other failure was a Winchester 165 grain factory load. The bullet hit a 150 pound doe at 125 yards, hit a rib, and barely made it to the heart. The other two deer I have killed were head and neck shots. (My dad's deer was the one with the raking shot).
