A fixed head will out penetrate a mechanical head, that’s a given. It’s the “failed to open” that I don’t buy. The first shot was most likely a shoulder or high backstrap hit that did not penetrate very far. I’d like to know exactly what head it was and see some pics. I’ve heard this failed to open excuse too many times only for it to be proven wrong. That seems to be the number one excuse for people that don’t like mechanicals and have very little experience using them.
Whatever lol. He shot the bull with 2 mechanical heads. One failed to open and neither was a shoulder hit or high backstrap. The bull died after being shot
4 times. 2 mech heads and 2 Magnum Buzzcuts. As far as excuses, I don't need an excuse since I will not shoot an elk with one. They won't penetrate and hold up like
a fixed blade although people have great experiences with them.
