I just got done with a whitetail hunt and tried to do a little bullet testing, but wasn't successful in recovering a bullet. Tried a frontal head on shot on a doe, with bullet place between the front shoulders and the bullet just created a huge wound channel blowing out an 8 inch section of hide behind the neck but exiting the hide about 12 inches beyond in tact. Bullet performance in the other two kills was identical. No evididence of the bullet blowing up, just massive wound channels with very little blood shot and instant kills with all three deer. I also had similar experiences this year with a 5 point bull elk. So, while I was worried about these bullets doing their job, I think they are just fine.
