Nice yote! I shot jackhammers for 6 years with nothing but great success, they are an awsome broadhead, I swore by them until I shot a buck quartering bad, I hit him perfect but I think it deflected and went between the hide and ribcage. needless to say I never found him and im sure it could happen with any expandable but Rage came out the following year and ive shot them since, the jackhammers leave one hell of a hole though.
