I have a Cabelas tumbler I use with corn cob media and brass case polish. I usually run the cases for 3 - 6 480 second runs in the sonic (giving the recommended break time to the sonic cleaner so it can cool down) and then transfer to the tumbler with case polish and run there for however long it takes.
I wet tumble with stainless steel pins. After you see the results you will never be satisfied with any other method. The last once fired brass I bought had been tumbled in corncob by the seller. Being disappointed with its dingy appearance, I immediately recleaned all of it by wet tumbling. Result was like new shine inside and out. I am spoiled now and can't live with anything less.
I'll second Marshall on stainless steel pins and tumbling. I used to use corn cob media and my brass was always "dusty" and had media stuck in the primer flash holes. Not so with the stainless pins and wet tumbling, the cases are clean inside and out including primer pockets.
vrkar10, here's another source...stainlesssteelmedia.com.They sell a 2lb "refresher kit" for $20 if you don't need 5lbs. That's what I got when I started. The pins come in 2 sizes, .041; & .047". You can't use a dry media tumbler for this. I went to Harbor Freight & bought a 2-drum unit for $56 & I split the media between the 2. The mix I use is purified water to just above the level of the brass in the drum; 1/4t citric acid powder & instead of Dawn DWD which didn't give me the brilliance I wanted I tried some Pro-Force Heavy Duty Degreaser, 1T, & it's $7 a gallon at Sam's Club. I got a very fine mesh wire strainer at Pier 1 to catch the pins. Rinse all the cleaning goo off & dry the brass then bag them to keep as much air away so they'll retain their brilliance. Good luck, jd45
