It's not a high percentage shot, but more importantly, if I'm going to shoot them, I want to kill them, not wound them. I've tagged two at 525 and 535 with 77 SMKs. Both times it's knocked em down, but neither were convinced that they were dead. One was flat on his back, all four feet in the air twitching, then he rolled over, looked around and walked into the hedge row. The 77 SMKs just go right through. Blood but no body.
