I just bought a caldwell to try out, it seems to work alright its got adjustable legs, and will attach to virtually any rifle, they only thing I would worry about is the foreend flexing and causing POI to shift, but I will mainly use it for my kevlar varmint, plus it has swivel and cant, too, most of the time I use a stoney point pole cat non attaching bipod works great and adjusts to any terrain
