I made my first reloads over the weekend in .45 ACP, and went shooting this morning with my brand new G21 gen4, and my Colt Combat Elite. Anyway, my first reloads were with Unique, and I was loading Hornady 230 grain ball and Hornady 185 grain XTP's. I started with a soft load using the 230 ball with 5.2 grains of Unique, and a OAL of 1.25. I also tested these bullets with 6.0 grains of Unique and a OAL of 1.25. These all shot fine and seemed to be quite mild. Finally I tried the 185 XTP's with 7.5 grains of Unique with a OAL of 1.23 All of the rounds cycled and shot very well with no FTF's or FTE's. My question is, using the 230 ball, and using the 185 XTP's.......what is the Max load using Unique? Should I keep going up in .1 increments until I see a problem case or primer deformation? How does one know max loading short of a KB? At 7.5 grains with the XTP's, there were no signs of overpressure and the cases looked fine.
