XTP's have killed a bunch of deer. I've added a few to that total

. They work very well, and for the price may be the best all-around deer bullet for use in modern muzzy's. IMO there are better bullets out there, but you will pay good $$$ for them.
My only criticism is that the jacket can separate from the lead core and fragment at very high velocities. This has happened to me once. However, the result was still a boom-flop.
