FWIW, I did not deliberately shoot through the "awful lot of brush", I ignored it because I didn't think it was actually in the way. Bullet path was at the top 1/4 of the hat in the second photo, just above the green leaves. Things do look different in good light. The shot was at sunset, I was facing West, and I couldn't even see most of the twigs without leaves on them - they were the same colour as the elk hide behind. I was using what I consider about the best possible scope for the shot, a Leupold 1.5-6 set at 2X, so I can't fault the equipment. Knowing now what I didn't then, I should have taken a neck shot. And I don't take neck shots unless I'm very, very sure of placing them exactly in the vertebrae. Too easy to wound and not kill outright. The entire neck & head were in the open. Animal had paused. I was using shooting sticks and the crosshairs were steady. If in my place you would have truly passed up that shot??? I guess we're all different, part of what makes life interesting.
Rather than questioning other people's shooting ability or judgement, in our camp we advocate taking any shot we feel comfortable with. But if the shooter draws blood, and he does not recover the animal, he is done for that year and hangs his tag on the "wall of shame". Or he isn't invited back again. The policy has a nice self-regulating way about it! We have never had to un-invite someone for reckless wounding. But lots of "shot opportunities" at 300 yards plus were turned down over the last few years. So far we have lost three animals out of about 80. Amazing how well camp members and guest hunters can self-regulate their behaviour when there are consequences. Works for us!
