dont all sigh!
just wondering to how the position came about? if you asked someone with an air rifle, who is not familiar with FT to shoot kneeling, it would not be how our rules state. the stance we adopt, appears very artificial and very un- natural. so how did this stance evolve? the natural for most would be to sit on the rear leg as it gives stability. i am making an assumption that hunters would shoot in this manner if long grass obscured their quarry. i could not foresee anyone adopting our take on kneeling. so was it to make the stance a little more un-stable?
i'm not perfect, but I shoot FT, reality is this is pretty much the same thing!
