Google RMC - Rocky Mountain Cartridge Company. Lot of discussion on the internet single shot rifles sites about RMC's turned cases and what they are made of. Try ASSRA.COM first.
I have a box of RMC’s in 32/40 purchased some time ago for Breech Seating my Schuetzen Rifle. One problem RMC had with rifle cases is turned does not have the same "spring" as a drawn case. They did not work well for me, hard to extract. Drawn expands when fired then goes back to near unfired dimensions which allows easy extraction while turned expanded and stayed expanded. I understand they have cured the problem with the temper of brass used. And considering Shotgun pressure vs Rifle it may not be a issue in the 10 G
