Maybe I'm crazy...I am thinking about trying a 300 WSM or SAUM in an 18" barrel. Does anyone have any experience with a short mag in a shorter barrel? I realize that these cartridges weren't exactly designed for short barrels. What I'm looking at is running this on a short action with lighter bullets (maybe Lapua 155?). I would also imagine this would be very loud and have severe muzzle blast. Or would I just be better off sticking with a 6mm/6.5mm and just accept the velocity loss. My main goal here is to have a compact rifle with the least wind deflection in these high winds in ND.
