I have 230 gr Montana Gold RN bullets. I have Power Pistol for the project. Data I have says 1.26 oal, 7.3-8.1 gr of powder @ 916fps (4.4 inch barrel). Thats from Alliant directly. I am loading for a basic chinese made 1911. It actually shoots pretty good but I don't have easy access to the gun as it's my father in laws gun. I am going to test some in my friends Commander and just check them for function. I would normally just end up with a midrange load anyway so I was thinking of just loading a small batch of 7.3, 7.5, 7.8 @ 1.26"and just see how they chrono. Any other advice for loading .45ACP?
