Why is there plenty of load data for 44 mag using universal, but none for 45 colt ruger only loads? The max load for 250 grain cast bullets is 7.8 grains. Hodgdon lists this load at 941fps. I believe the speer manuel says it takes almost a whole grain more powder to get this velocity. Also unique is supposed to be about the same as universal and those loads. All for I believe 9.5 grains.
