Because I was the primary service center for Cimarron for over 10 years, I have accumulated a lot of brass over the years from test firing their guns. These are Black Hills cowboy loads, but the brass is Starline. It's all once-fired, but since cowboy loads are pretty light, the brass hasn't been stressed too much. I know components are a little hard to come by, so I'm happy to share what I have. The calibers I have the most of are .45 Colt and .357 Mag, but I also have .38 Special, .44 Special, .44-40, and maybe a few others. If you need a box, let me know and I'll be happy to give you one. The only cost would be shipping if you need me to send it to you. You can text me at 830-456-8613 if you want.
