[quote="juststarting"]I am noticing that when I tumble cases .223 and .308 using walnut media in a little baby tumbler, the cases come out shiny shoulders down. However, the neck still has carbon/burn residue. Especially, the area where the shoulder and the neck meets.
Stainless, pins, water and real burnishing compound is the only thing that will do the job correctly. I use a tumbler from aussiesapphire.com.au and their burnishing compound. Lyman has a good pin tumbler as well.
I have a large and medium sized tumbler drum. The smaller one does a few hundred 223 or 100-150 303 cases and up to 300-350 9mm or 200 or so 45ACP cases.
The large drum will do about 600 x 223, 400 x 303, 1000 x 9mm and 600 x 45ACP at least. Smaller loads take less time. For example, doing 200 x 223 takes one to a maximum of one and a half hours in the small drum. Same time for the others I've mentioned. In fact I never, ever run longer than 1 1/2 hours.
I suppose I'm not telling you how to get better results with dry media, but I doubt you ever will.
The logic behind cases shedding weight as a result of steel pin cleaning is ridiculous. You would have to have them tumbling for a day before you would see even a few grains lost. The cases in this photo have been tumbled at least 8 times, the number of reloads they've had.
