I hunted with them for years, back in the 80s I think. They flew great..... BUT the blood trails sucked. They're less than an inch and really don't put a lot of blood down. I shot a lot of deer with them.... but NEVER had an easy blood trail. Too many good broadheads out there to go with these. Dump 'em or shoot woodchucks with them or something... but don't use them on deer.
