Any adjustable bipod or tripod will work. I got a spring bear this year using that very technique. Rifle forearm was resting on the bipod. I was sitting with my elbows resting on my knees, my non-trigger hand braced against the toe of the butt. It makes for a very stable, benchrest-like shooting experience. The only difference is, I was in a ground blind. One tip, I wrapped the cradle of the bipod in a short length of foam pipe insulation to make sure there is adequate padding.
