I fired one round in my 1914 Mauser (age determined by serial number) yesterday. I used W231 powder and liked the vertical line of impact at 7 yards with a cast bullet. I could not find the "unloaded" very small case. I want to load some more to possibly load FMJ's (nominal 71 grain) sometime. I will look for head stamped brass cases that I like before loading on a single stage press. I did not post powder charge info here but I used CCI primers. I use a Dillion 550 for 9mm, 40 S&W and .45ACP. I use a single stage press for .45 RIM (for a S&W 625). I also use moon clips in the revolver with .45ACP cases for the S&W 625.
I was range busy with people but I did fire three 9mm pistols and another one owned by a student. People asked me that CZ "thing" was when they didn't know what it was.
In closing, I have never tried a .327 revolver but I am thinking the full wad cutters might be interesting even in a Ruger single action revolver.
