Any reason to show off your gun you jump on it huh ?? I don't blame you if I had that rig I'd carry it around and shot it off like a childs photo !! Sweeeettt I wuld think that any gun that'll have at least 500lbs KE at 1000yds would work as long as you any hit that far , I would think that about any of your 300Mags and some big 7mm's would work good.
