I recently started a thread about the empty cases being difficult to extract from a stainless .357 Blackhawk. I'm shooting a max (16.6) load of H110 and 158 gr. XTPs with SPM primers. I fixed the problem yesterday.
I got a felt polishing tip for my Dremel tool - it's tip #422:
These were the steps:
I cut the pointed part off, making it cylindrical. Then I installed it into the Dremel chuck deep enough that it wouldn't go into the throats, only the chambers.
Then I ran it against a piece of sandpaper for JUST a second, to reduce it enough to fit into the chamber.
Loaded it up heavily with chrome rouge - usually called 531 or CR1. Use minimum speed on the tool to do this.
I flipped it up to full speed (25,000 RPM) and polished the chamber for 3 or 4 minutes, moving it around steadily and evenly. It's VERY important to keep moving it around like this. I reloaded it with rouge several times during this process. You can't use too much.
Cleaned the chamber out with a brass brush and some Hoppe's #9. Dried that up with a few tight dry patches. Wow - looks like a mirror in there!!!
Mark that chamber with a Sharpie or stick in a little wad of paper.
Repeat for the other 5 chambers. Clean everything up, reinstall cylinder.
Presto - the fired cases almost fall out. Problem solved!
Thanks again for all the posts. There were a lot of good suggestions and advice from the forum, all very educational and appreciated.
