Due to being limited to a COAL of about 2.65 (instead of the standard 2.8) in my .308, I am running into real estate issues with powder in my shells with Varget. Does anyone have a guide on grains per cc on the following powders? Am trying to figure out if there is a load that would give me more breathing room over Varget.
