RE: Penetration at 60 yards?
Here is another little test you can do. Get a person to stand behind a solid arrow proof structure and attach a rope to a target. Instruct him to snatch the target the instant he hears the bow fire. Do it at 20, 30, 40, 50, and 60 yards. Come back and post your findings.
BTW, I am not calling, nor have I called, anyone here unethical. I am also not saying that it can't be done. Just that the vast majority of hunters shouldn't even think about attempting it.
Simply making a point about hunting live animals instead of shooting stationary targets.
BTW, Fred Bear was in a very elite class of bow hunters that very few will ever achieve. Byron Furgeson is another.
