In lieu of a bipod, I use my trekking poles. With the handles crossed through the straps of each pole, it makes a very sturdy rest for sitting or kneeling shots. The poles are sturdy enough to really lean into them, and the tips dig in really well to most surfaces. On the rare chance the scenario allows for a prone shot, I use my pack for a front rest, and bino harness/hat/gloves/whatever as a rear rest. If you practice with the trekking poles you can get some surprising accuracy using this setup. I've only shot three animals past 350, but all were sitting using shooting sticks for a rest to get above the sage brush and all were DRT. I also find them very quick to deploy and to adjust the height on. My friends think i'm crazy for carrying trekking poles on antelope stalks, but then wonder how i can get setup for a clean shot while they are still fiddling with bipod legs. With that said, there are certain applications where i would probably choose to use a dedicated, gun mounted bipod.
