I found a way to cut the size in the camera, but only got this one pic before the battery died!
I cut the channel (ugh, what a pain) it took me about two hours, a cut off grinder, two 5/8 aluminum oxide dremels drums, and a sanding drum. Finished off with cold blue, added the Konverter ring, and the Richards ejector rod, and went out and capped off five rounds of Black Hills 250 45 Colt into the grounds in the back yard (nice to live in the country).
I now have a Richards in 45 Colt (5 shot) the hammer locks between rounds like an R&D (sort of). If I feel the need for a second percussion for Plainsmen or CW re-enacting, I just replace the rammer and the cylinder
