I developed a 45 ACP +P loading that I am very happy with and I thought I would share. This is it: +P Brass 230gr Zero Brand JHP 8.1gr Power Pistol CCI magnum LP Primer AOL 1.234" medium crimp I find this load to be very consistent. 1000fps measured consistently using my Chrono out of a 5" barreled 1911. Out of my 3.25" barreled PT145 it measures consistently at 900fps. Recoil is obviously quite stiff out of the PT145 but not that bad out of the full size 1911. If you choose to use this load use +P brass. It is a safe load I see no pressure signs on the brass or primer.
