RE: let's talk about BHs and hitting bone...
There are several good broadheads out there that will hold together and bust bone. The ones I would stay away from would be mechanicals. The strongest would probably be the cut on contact heads, then fixed/replaceable heads like the Muzzy/Slick Trick. I've stuck a some Muzzy 125 3blade right down through the spine from almost straight above and a couple that went either through a leg bone or through the opposite shoulder..most I every had to do was replace a single blade once in awhile.
