As I mentioned,poor bullet placement, too great an angle in the shot, or improper selection of the bullet to begin with. I bet most of those instances were with magnum loads of of bullets designed for slower velocity.Myself, I have never experienced any of those.However,I am not a shoulder shooter.
Actually, no. I think all of those instances were 170/180 grain 30 caliber bullets. 30-06, 308 and 30-30. One 30-30 was a 160 grain FTX Hornady LeverEvolution, so it may have been a little fast at 15 yards
