I tried doing a search and couldn't find much info on this cartridge. Has anybody experimented much with it? I was thinking about putting a new barrel on an EDM Windrunner and seeing what kind of speeds I could get from it. Maybe 3400 fps with a 350 SMK. I'm sure it would be a barrel burner but what a fun way to burn a barrel. Are 350 SMK bullets hard to come by? Can you only buy them through Cheytac? I'd imagine this thing would be supersonic past 3000 yards.
