I prefer shooting 45 Auto Rim in my Brazilian Contract because I hate loading and unloading moon clips.
These pistols are not that accurate, they go bang, and will function. Do no hot load these things. These are from an era where unheat treated components were common.
I have chronograph data below, but now I am using 3.5 grains Bullseye with a 250 because I can also shoot the same load in a converted Webley.
Lead bullets of .452” leaded in my barrel. I found the .454 diameter lead bullets to be better.
My Brazilian will shoot to point of aim with standard 230 FMJ ball. It shoots high with heavier bullets.
