5744 loading:

Fill case to base of seated bullet; multiply by 0.4; that will provide velocity to 40% to 50% of full-power. Load up to 48% for max lead velocity loads. Max velocity & pressure between 60 and 65% of full case capacity.

From Terry Weiland's book. 5744 is pretty flexible as long as you start low and work up to a modest velocity. Bob
