with the 245 Powerbelt and with clipping shoulder and hitting the spine, i call is success. You should see what happened with saxmans deer with 2 pellets and a lung shot. Maybe 25-30 grains of bullet was all he found.
Thats funny how the base stayed on. Have him pop in on and off a few times and spin them around.
Another thing though, i think that HP held up a lot better than what the aerotip would have. The Aerotips have a bad habbit of pushing through the center of the bullet, weakening it.
