I'm working up that load right now for my Springfield 1911A1.

Based on data obtained from my Midway LoadMap and a couple other sources, I'm starting with 3 loads: 5.4, 5.7, & 6.1gr. - these show to be light to medium loads.

This is my 1st attempt in .45ACP (along with some 200XTPs and 185 Golden Sabers) - so Tuesday at the range will prove interesting - I can't WAIT!

Oh - for OAL, the LoadMap says 1.275" - but that didn't seem to want to cycle through the chamber, so I dropped it to 1.255". Pressures should still be safe at that level with these loads. I'll know more on working OAL when I see how these cycle when fired.
