I have not test them on game, but I got one of the sample that they sent out. I tried shooting it into newspaper and card board and had the blades curled up. I'm not sure if I want to use them on game.
Yes this will happen but only if the blades are not very tight , you must hold the blades in a BH wrench and tighten the lock collar w/ pliers.
Here is the buck I shot last year w/ a 125gr sonic. Blasted through both shoulders and shaft buried about 12'' in the rocky dirt behind him, all blades intact!
