I find it funny how so many people always blame equipment (Bh's etc.) when the problem lies in shot placement and/or their own mistakes. Crap happens even to the best bow hunter. I have not been bow hunting that long. The first thing I learned from my mentor was shot placement. "Take away their ability to breathe and you win every time""Wait for the right time and angle" "Aim for the exit hole" With this advice I have stood next to every animal I have ever shot at. Will I ever lose an animal? Probably one day I will. Know your limitations, that bow is not an 30.06. Why would you even try to take a shot like that? Especially on the biggest buck you have ever seen or a doe for that matter? I have read every excuse in the world on here and other places. My mech. broadhead didn't open or it opened up in flight. Or muzzys suck, no blood trail with a stinger etc. Most of them will work perfectly if the shot placement is correct. No the bloodtrail might not be that good or it might be great with almost any head. I am by no means an expert, never have I claimed to be.
