I have a CMMG MKG in both rifle and pistol configuration. CMMG tells me (and the rest of the world) that their MKG is safe to shoot .450 SMC ammo which has the same pressure constraints as the .45 Super. Super brass is readily available. I can't seem to find much (if any) reputable load data for either cartridge. Any one have a source for REPUTABLE load data for either cartridge??? Thanks.
