Brass is starting to corrode

[DTS]

Rotary tumbler with stainless steel pins. They will shine like brand new.

Cliff - am I to understand you do not clean the cases first, just put them in the tumbler and let 'er roll??

NOT Cliff here......but I have the same rig.....SS pins & wet tumbling.
If I cared to, I could come home from a match, dump into the tumbler, let'r roll & a couple hours later....presto - clean.

Could even let dirty cases sit around a day or three before going in.
Of course this is only my experience & using genuine gunpowder.

I don't use this direct procedure because the tumbler/process requires a lot of my workbench space.....and, I mostly shoot C&B so there are typically only 60 of the 44-40 cases after each match. Besides, I have enough brass to load once & shoot all year. Case cleaning takes place near the end of the shooting season, larger batches = more efficient for me.
