anybody ever heard of these? i was at gander getting some arrows refletched and was wandering around the store and they had a video of these things in action. they looked pretty incredible. they look like a field point tip, but have 4 2" blades sticking straight out from the end. basically, if the shot was right, the turkey's head would just fall off. im going turkey hunting for the first time this spring and cant wait. i'll be using a gun, but these bh's looked pretty incredible. anybody else see em or have an opinion on em?
