Back to the topic, the OP has a point - although a small one.

I for one, don't mind posts on "form" at all. More power to people trying to improve. However, I do think hunters should be less concerned with perfect form, and more concerned with practice in less than perfect positions. I have shot many big game animals, and I'm not sure I've taken two shots from exactly the same position. Sometimes I'm kneeling, sitting, crouching or even standing. My body is usually at an angle I'm not most comfortable with. I often hunt in very thick undergrowth and all this is necessary to get around limbs, trees and other obsticles. At times, I'm in a ground blind. At others, I'm in a tree stand. I stalk on quite a few hunts. Combine this with unknown angles that animals approach and the odd positions one can get into are many.

I practice shooting in these positions all the time. I never shoot with only an open stance or closed. I vary it as much as it can be varied. I learn what to expect from each position and I'm confident I can pull off the shot or I don't take it. In order to pull this off, not only is a lot of practice in these positions necessary, but a tad shorter than normal draw length is beneficial. The only real critical form factor for me is to try to keep my shoulders in a plane perpendicular to my spine while hitting my anchors. Other than that I'm all over the place and that's how I like to practice.

I've seen more than one superb target shooter who was a miserable shot when hunting. Hunting success can be attributed a lot more to practicing hunting situations, than practicing perfect shooting form - in my opinion. Practice perfect form, but practice varied hunting postions at least twice as much.
