I shot a buck, using a 345 gr. aerotip pushed with 115 grs. of 3f/trip. 7. I was shooting an Omega, at about 40 yds. It killed the buck but the bullet completely came apart, not even leaving a mark on the oppisite side, I believe that I woluld have had a wounded deer if I would have hit the shoulder instead of the ribs. I am going to use something else next year,probably a Barnes (if my gun shoots them acurately) Good hunting.
