I have a gun I've thought of modifying to 10mm Auto Mag.

with full moon clips, since Starline makes the brass. All in the world it's a rimless Herter's by sheer accident and specification. I'm a champion procrastinator so I may never do it.

I once also made some "rimmed" 10mm auto rounds. Six actually. I finally got them to work but it was not easy. The rims had to be turned way down due to interfering with the pawl gear on the gun I have. It still had to actually headspace off the case mouth. It was quite an exercise in futility, but I learned a lot. I made them from .30-30 and had to inside neck ream the brass too. Very labor intensive.
