As others have mentioned there are tons of items in my pack I can ball up and stuff under the butt end of my stock...however, there are plenty of cases when I drop my pack to crest a ridge or climb up a rocky knoll where I ultimately end up shooting from. I run a Harris 9-13" bipod, which, unless you are shooting uphill, will cause the butt end of your rifle to "float" even on the lowest setting (9")...In these situations I have found the Triad Tactical "Down Under" support invaluable. Weighs less than a few ounces and while prone I have shot past 1,000 yds on steel with ease. Similar idea to how Ryan Lampert uses his sitting pad folded in half when he shoots. Have one on each of my rifles, too light not to.
