I shoot a 7mm mag and use Wichester CXP3's in a 175 grain(the box says they are excellent for brown bear,moose & elk)lol.
Every deer(at least 40) I have shot with them,from 20 yds to 200 yds,have been a bang flop.
But now,with that being said I have shot 3 deer at 80-100 yds +/- that the bullet did not exit,but it did knock them 3 feet sideways DRT.Also have a buddy that shoots a 7mm w/154 grain BTSP and he has had it happen to him once.
Always thought that was kinda strange.
