I quit using the bipod on this rifle (7mag) because my groups would always seem to grow when using it. Strangely, accuracy even seems to be affected by simply having the bipod mounted on the gun, folded up. It's worse when it's actually being used though. I'm thinking that maybe recoil is causing the un-stiffened stock forearm to flex up and hit the barrel, throwing it off, before the rounds have exited, due to the extra weight of the bipod. Does this sound like what is probably happening with the bipod attached? Has anyone else ever run into this? My new Choate Ultimate Varminter stock arrived yesterday, but it won't see any action until my new stainless heavy RUM barrel arrives, hopefully within the month of April. That stock DOES have a considerable amount of (aluminum) stiffening molded into it. It has a thumbscrew near the butt for elevation adjustment, when used with a bipod, So I want to keep the bipod mounted on it, and use it whenever feasible. Will I be free of the group growth problem with this stock, when there is a bipod mounted and/or used?
