Seems to me if you do any amount of BG hunting, eventually you are going to be faced with a situation where you simply have to shoot from an unsupported, or less than ideal,shooting position.
Not that we don't do our best to quickly assume a rest or some support if we can, but it's going to happen because we are dealing with unpredictable animals and situations. So, it only makes sense to have some degree of proficiency in a variety of positions. Our own practice sessions will tell us what our proficiency levels are.
This does not mean you get wild eyed about it, but seems to me most of us know almost immediately which shots we can, and cannot make, on an animal.
My first moose was such... 125ish steps... offhand. Was the only choice and a quick choice... bull was going to leave. I put the gun up and knew i'd have to make a choice. But they are so big it was easy and I was not out of wind at the time...
I still think that most times you benefit more from practicing field expedient shooting....
And in hindsight had I been thinking that morning... I could have quickly sat down and popped a shot off as quickly and more accurate... it did not dawn on me that quickly... though a knee or butt would have been damp or wet...
