RE: The search for the right mechanical BH
Rob,
If you shoot something with a broadhead, retrieve your arrow, spin test, and sharpen or replace the blades there is nothing wrong with re-using them. I have killed more than one deer with the same head.
Why do you say that ALL broadheads are one shot and done? I sure dont think SilverFlame users stop shooting them at game after one shot if they are in good shape.
I know I have Slick Tricks that have passed through several deer.
