Cadillo, so far I have not found out. What goes wrong? I place dirty black powder cartridge and smokeless cartrige cases, spent primers still in, in a Model B with just enough water to cover and a teaspoon of citric acid powder plus a squirt of dish soap. Try to do batches of about 3/4 full in the drum. Let'm tumble until I sober-up and they be like new. I rinse in clear tap water and drain while in the sink. While they are still damp I toss in a dib of Lee case lube and mix with my hands. Into an Orange sack and air dry a few days The case lube leaves a slight haze, after going through a progressive press, the ammo looks new. Looks new still when shot days, weeks, or months later. No stainless steel pins used. Will my cases go bad doing this over time?
