Thanks for your reply. That's what I was thinking too, common sense. I saw the new bows he had for sale and how small they are getting why not the broadheads??? I have a older Golden Eagle I'm getting some new stuff put on and complained about poor penetration. It's set at 70# shooting 100grain Thunderheads. I've used mechanicals and got the same poor penetration. Both shots were 20 yards. I guess both could have hit bone somewhere.
