This is why powders like N32C , Unique and Red Dot are popular amongst gallery rifle shooters. They have a larger volume per grain than other pistol/shotgun powders. I find that they meter really accurately as well. I throw my powder in an old Redding thrower with a competition dial on it and its superbly accurate with Red Dot.
