Alright, I shot a box from a bipod this weekend. I sold all of my BR equipment so, I had to use an improvised rear rest that is not too disimilar from what I would use in a tactical centerfire competition. I shot groups on an ARA card and couldn't garner any quantifiable evidence because my CZ is such a POS, it really can't be relied upon to put anymore than two bullets where they are supposed to go. Given a solid rear rest like a protektor bag, I don't see why you wouldn't be able to do this with a good gun. I have a LOT of time shooting off of training wheels(bipod) and consider myself fairly decent with the sticks. I would two shots or three shots to bughole and then one would flip it's way a quarter of an inch off. In watching my reticle I am confident that it was the gun and not me(how could it be me??? hehehe). So, if you have a gun that is consistently printing 5shots into the .1's (minus the bullet diameter) off of a bipod, I think you could do just fine with it. I do not prescribe to the idea of having the bipod on something slick so that it recoils freely, I have never shot a gun off of a bipod in a free recoil situation, I just think it is mechanically poor to do so. I pre-load my bipod by applying forward pressure to the legs, pre-load the trigger and break the shot when the wind and my heartbeat presents the right sight picture. I would like to say this "test" was fun but, it was more frustrating than anything. Having a gun that you don't have any confidence in sucks.
