If you are hard on it you might want to look into FLM dog bones. I read a lot of great things about them. I've broken 5 dogbones in 1.5 gallons of gas on on a Savage X 4.6rtr. I just got my FLM dogbones the other day but they are SO much stronger looking than stock I doubt I can twist the head off of them. The price isn't a whole lot different then for stock bones either.
