When I first started deer hunting on foot, I knew that my range work from a bench would not translate well to field performance. Accordingly, I bought all manner of shooting sticks and bipods and such to use as surrogate rests. When actually afield, I determined that, for my purposes and how I hunt, they all just sucked.
I found that shooting sticks were a pain to carry around, the collapsible ones often rattled and were slow to deploy, and generally the sticks didn't give me much real lateral stability. Bipods were worse - they were heavy on the rifle, bulky, awkward to deploy, and in many cases only useful when prone (which usually means losing sight distance, and in north Texas often means flopping down in a bunch of prickly pear or sharp rock).
In the end, I found that shooting offhand or kneeling for shots out to 90-100 yards worked best for me (especially since shots tend to be fast) and finding improvised support objects in the field was best for anything longer. I shoot from the knee a lot, and can drop to a knee and steady the rifle forearm/support arm on the weak side knee pretty dang fast (even for an old guy). Shooting from the knee is about as laterally stable as the long bipods/short shooting sticks, doesn't cost anything, doesn't increase the field load, and is a whole lot faster to get into.
If I'm stalking a herd that's doing a midday feed, then I'm using curve of the ground and scrub vegetation to my advantage. That usually gives me a bush or tree or something against which I can pin the forearm of the rifle, and that's plenty steady both laterally and vertically for most shots. If I really *do* need to go prone, then I can always use my pack or local objects as a forearm rest if I don't want to trust my prone position technique.
My point is that I have learned that it's better to figure out how to shoot from real field positions rather trying to take the range with you into the field.
Just food for thought.....
