The Stainless Steel Pins for tumbler media work great. I recently bought 5# of pins for use in my RCBS Sidewinder. A teaspoon of Dawn, 1/4 tsp of Lemi-shine (from Wal-Mart) and 1/2 gallon of water cleans a load of brass. It does take a while, about 4-5 hours depending on quality of brass going in. This process even cleans the crustiest military brass and makes it look like it just ran off the end of the production line.
The "pin" process doesn't shine the brass like jewelry but it is clean and bright. Primer pockets and the INSIDE of the case are clean, totally free of any carbon from the previous firing.
When the tumbler shuts off I merely pour the brass, pin, and solution into the case/media separator and separate just like with dry media. Pour off the dirty solution, replace the pins in the tumbler and get ready for another batch.
As for drying, I just leave the brass in a box lined with a couple layers of paper towel. Shake it a couple of times and let dry overnight. Once the brass has been "processed" once with primer pocket uniforming, neck turning, and flash hole deburring, it's only a matter of tumbling, inspecting, trimming if necessary and then reloading.
It's like shooting a handload that is made with new brass, everytime. Cases actually look better than those of most factory loaded ammo.
No more dust and lead contamination worries. Lifetime media so no more searching for a good deal on lizzard litter or ground corncob in smaller than 50# bags.
Only downside is that it doesn't work in a vibrating case cleaner/polisher. I'll keep mine for any cases I want to polish with a "jewelry like finish".
