With 70 grain bullets, I get equal velocity between a 24" 6x45 P-Dogger and an 18" 243 LBC (which has slightly more case capacity than a 6 ARC). Both ARs. That should give you a good reference point on what to expect. I'm a big 6 ARC fan and like it over Grendel, but I'm sticking with the 6x45 for the filthy disease infested rodents. The hassles of ARC in the current environment (brass and powder choices) aren't worth the few extra fps.
Let's go Brandon!
