Excellent post. Thanks for taking the time to articulate it. As you said it's basic and maybe is the reason we (read, I) don't take the time to think about it often enough.

I'm not an inexperienced hunter and have shot my share of game but for myself I'm going to being doing a lot more off hand (kneeling, standing, prone, sitting, tree and other rests) practice shooting this summer and fall. I missed a nice buck last fall that I walked upon and only had one offhand standing 80 yd shot before he bolted. I wished afterwards I had spent more time doing this type of shooting and less off the bench gg.

P.S.
I copied and pasted your post in an e-mail to my 2 sons and daughter with whom I moose & deer hunt with.
