I've experimented with dozens of different types of b-heads, fixed blade, replacable blades and mechs. I've tested them on critters and other different medias. From steel drums and plywood, to old stoves and fridges. MY all-time favorite b-head, the one that has impressed me the most with ANY hunting rig, is the Rocket Steelhead. This b-head is THE best flying, hardest hitting, and deepest penetrating b-head I've ever witnessed. An outstanding pruduct with an incredible reputation. Thsi head has become my ONLY choice for that shot of a lifetime. You simply must take a serious look at 'em. Good luck and good shootin'
