Case cleaning
Ugaarguy--You asked, "Is there any way to clean cases other than using a media tumbler that you folks recommend?" (Emphasis added)
Short answer is "NO."
Tumblers are cheap, last for years, work for you while you do something else, and the cases come out needing no further handling, drying, etc, etc. Ready to begin reloading right now. What's not to like?
Other cleaning methods, given smokeless powder and non-corrosive primers, include liquids to be drained/dried out of the cases, or labor-intensively hand-cleaning each case. I've tried both. Can't reccommend either.
If the cases in question are cruddy enough to warrant that kind of cleaning, I'd seriously consider recycling them and buying new cases. Well, also given that the cases are not particularly rare or expensive.
Replacement brass for "common ordinary cartridges" is easily available as free range brass in most locales, or cheap as once-fired @ a gun sho.
