I had an idea today to try fireforming PPU brass without annealing using trail boss powder since I have a couple 9oz containers of it. It worked great on the 3 I tried. The load was 7.5 Rem Primer, 2.8 gr of trail boss with a 20 gr Varmageddon tipped bullet. One container of trail boss should be good to fireform 1400 pieces of brass
