i have a couple of friends with an odd problem that i dont know the answer to. their long range setups is the exact same setup which is: a factory remington 300 ultra mag with the fluted varmint contour barrels. they are both shooting 210gr bergers with 92gr of h1000(velocity ~3050fps) fed 215m primers. nightforce scopes...... these guns shoot ~2" groups @200yards. their problem is, when we are out shooting at 800-1200 yards, their guns always shoot to the right! i myself shoot a 7wsm with 162amax @3050fps. the other day we were all 3 shooting at 800 and 900 yard steel targets and i was dialing for little or no wind and they were dialing 2 or 3 moa. same thing happened to one of them when we shot at 1200yards on a different day, he had to dial 6 moa when i was at 2moa windage.....pretty calm day. same thing happens to him at his range at 1050yards. now when this all happened when we we're all shooting prone and off of bipods and sandbags. i dont really know how they worked up their loads, so thats questionable. if it was their loads though, it would be more of a vertical problem rather than a windage problem....right? i do know that they do not put these bullets into the lands. they load them short enough to fit into their box magazine...that may be a problem. they use swivel bipods....ive thought that maybe they are getting torqued while shooting(i use a fixed bipod). i may have to shoot one of their guns on my bench off of my rest. they are convinced that their twist rate is not fast enough for the bullet. they are ready to sell all of the 210bergers they have b/c of this. any ideas?
