Only deer so far. But when get back out to Colorado they will still be my broadhead of choice for elk with out question.
My close second choice would be a G5 Striker. Same 100% steel construction, sameGerman blades, and a very good blade retention system with these heads.
Of all the broadheads I have used, tested, and carry in the store these two are my top picks above all others.
Oh, and cinder blocks and steel drums.
So far, in every targetI have shot them into they have out penetrated the competition andin anydestructiontest I hve donethey haveheld up better too.
