Folks won't realize that. I have tried to dig the bullet out of every deer/elk that I have shot. The worst case was a little doe that I shot in the chest head on with a .243 in Texas. It virtually exploded everything in her chest cavity and I recovered only some fragments. The best was an elk shot in the upper right hip with a 30-06 Silver Tip. I still have the bullet somewhere. It is almost a perfect mushroom to about 1/3 again the diameter. We used to shoot at just about any and all things for plinking and I have seen some .22 LR bullets that in no way even resemble a bullet. I have seen some that look like they could be re-used. Ballistics are a strange science.
