I shot a small buck, this year, using a 345 gr. Aerotip. I used 115 grs. of fff/triple 7. First let me say it killed the deer, with a chest shot, with about a 25 yd. run. That said, I would not use one again. There was about a 2 1/2" entrance hole. The bullet literly exploded, leaving pieces all over the place, didn't even leave a mark on the opposite side. I cant help wonder what would have happened if I would have hit the shoulder (nothing good). Good hunting
