Head shots are not unethical or poor percentage some of the time. I limit mine to 30 yards or less, on non-moving moose, or finishing shots close up.
My last one on moose was about 15 yards, using the snow machine windscreen as a rest. It's do-able..... at least with a 3.5-10X scope set on 6.....
The one before that was a near miss - about 20 yards, offhand, head on. He ducked and started to turn to run just as I shot. Took the top of his brain pan off instead of 'tween the eyes. An inch higher, and I'd have had to wing shoot him with the second - but he wasn't going anywhere, much.
