I saw a friend of mine kill a female red stag (he called it a hind) with a 50-lb fiberglass recurve and cedar arrow tipped with a bone point made from antelope leg bone. He double lunged it and it didn't go far. Heavier arrows work better, along with perfect arrow flight and accurate shot placement. After seeing what that antelope bone did, I KNOW a stone point would be absolutely deadly on a red stag. I've never known anyone who killed one with a stone point, so your buddy would probably be the first. Tell him not to even question whether stone points would work...trust me, they will.
