Upto an hour SS pin wet tumbling. Cases come out clean as a whistle

2 hrs w/walnut & nu finish. Never cleaned a primer pocket. I decap when I resize. Don't want to run dirty brass thru my die. Works for me.

Only about an hour in treated Corn Cob media, however....I first clean them in a Citric Acid wash. Best thing since sliced bread. Here's a thread from the Cast Bullet Forum that will explain:

Citric acid brass cleaner

I am an absolute believer in this step. Citric Acid can be found in it's pure form in the Canning section of the grocery store, and/or you can use Lemon Shine, a dishwashing additive that is largely citric acid. Virtually no harm to the brass (been doing it for years), and in fact...according to one of the posters in this thread (Scientist), it actually improves/reconditions the brass at a molecular level. I'm not sure about that, but whatever it does, it works. Give it a try, you'll like the result

I have stated before that the tumbler is a crock pot not a microwave. I usually tumble for 10 or 12 hours. I have lots of brass after a 40 year reloading career and am in no hurry. I use corn cobs and whatever car wax I have on hand.

About 2hrs I get my corn media from Anderson General Store try a going to a Pet store. You''ll get a big bag very cheap they''ll also carry walnut.

Just starting to reload. Have a federal arsenal oscillating bowl coming, going to petsmart to get walnut medium, and am going to try using a bar of red jewelers rouge to clean and polish with. The bar cost $8, and should last along time. Instead of waiting for the wet polish to dry in the walnut medium, I'll just use a fine grater to make about 1/2 a tsp of fine ground compound. We will see.

I find jeweler's rouge leaves a real mess. Use a capful of car polish instead.

really what does it do? waxy, smearing? seems like your taking out the drying process of the wet polish, and skipping a waiting step?

But if you have been there, ok. Nu finish it is.

This is my answer as well.

I used to use a vibratory tumbler with walnut from a pet store and nu finish. I would start it, go to sleep, and turn it off when I woke up.

For my birthday, I bought myself a Thumler's tumbler and stainless tumbling media from MidwayUSA. The difference is amazing. My brass is completely clean, inside and out, in only 3 hours. I went back and recleaned my 'clean' brass from the walnut, and was quite shocked at how much more filth came out of the insides. There is also no dust.

Use corn cob media in a Lyman 1200, with Frankford Arsenal polish added. I change out my media pretty frequently. I run a full batch of 300-500 pistol cases for about 2 hours with new media to clean, then I reuse the batch for another 300-500 and that usual takes about 3 hours for the same results. I then dump the media and add new stuff. I don't shoot a huge amount so an 8lb bag of corncob media, which is about $4 OTD at Wally World will last me about 2 years worth of shooting.

Decap then 4 hours in fine walnut with Nu Finish added, works beautifully as long as I put a reasonable amount of brass into the tumbler. No further primer pocket cleaning necessary.

2-3 hours works well for me. Don't have to pretty, just clean.
