I'm not sure I would like using this bullet. First off, the smaller pieces would have less chance of exiting and exit wounds would be smaller. Smaller or non-existent exit wounds leave smaller and non-existent blood trails. Second, the force of the bullet going through the vital organs and the shockwave it produces within the body does as much to put the animal down as the bullet wound itself. A bullet that seperates on impact will do more physical damage but produce less shock than a normal bullet. Less shock means a deer that runs farther possibly not leaking blood, see point 1. Now the upside would be, a deer hit with this bullet is more than likely a dead deer. It is doubtful that you could hit a deer at an angle that wouldn't cause quite a bit of internal damage.

I just don't know if you could find it.
