Lyman reloading 45ACP

[jrplourde]

My most recent Lyman manual treats 45acp and 45rim as two entirely different goodies. Different powders and different loads for the same powder. What's that all about? I would have thought they were identical except for the gun to be used.

I use the pressure tested data for the .45 ACP in my 625's. The SAAMI standards for the .45 Auto Rim show reduced pressure loads in deference to the very soft lead round nose bullets loaded by the factories. Apparently, the factory bullets leaded at higher pressures and velocities.

All of the revolvers were designed to shoot factory hard ball 230 gr .45 ACP cartridges and the same pressure works the same with Auto Rim Cases. I did a little study of the case capacity comparison and with the same brand of cases the capacity was the same. Everything else is the same, so I went with the ACP data.

+1 what dale said. I am running same powder charge of W231 in my auto rim right along side the 45acp

The AR & ACP have the same case volumn & I load them the same for use in my M625. I can load SWC & roll crimp though w/ the AR brass. I'm working up a load for some 250grLSWCHP thrown from a new mold I just got.
