I've seen video of just about every BH on the market failing to pass thru at some shot or another.Even with the best broadheads. I've seen BH's only go in a few inches.

As you well know a lot goes into if an arrow will go through an animal. What was the poundage of the bow. weight of the arrow, distance, shot placement, did the BH hit a rib, etc? Too many if's on 1 shot on 1 animal compared to the videos and tests I've seen of them passing with flying colors.

I've seen enoughto them doing well to make them the first mechanical I've ever used. if they do fail they will get tossed.
