Have any of you encountered your brass coming out of a wet tumbler discolored (I tumble with stainless steel pin media)?
I've been wet tumbling my brass for probably 4 years now, and normally the brass comes out looking like new brass. The lot I'm processing right now is Lapua brass for my competition rifle. I normally dry tumble briefly for the sake of keeping my sizing die clean, then size/decap, and throw the brass into the wet tumbler to clean it up nicely before loading.
This time I was tired when I started, and I tumbled wet before sizing. The brass came out perfect, as always. But, I decided to give the brass another run through the wet tumbler after sizing, just to get all of the case lube off. When I pulled the brass out after its second tumble, I noticed that it looked a lot darker than normal in some spots, and had uneven discoloration.
My recipe for this tumbler has always been very warm water, Dawn dish soap, and some Lemishine. I've always had great results in the past.
Any idea what might have gone wrong this time?
