I've been searching and researching and ended up getting the Thumbler Tumbler model with the two 3 pounds drums, A-R2 is the model number. I got into the rock tumbler being the vibratory types always seem to have issues.
With the two drums I can have both 7.62 x 54rs and .308 cases going at the same time and can keep them separated.
I also bought some crushed walnut shells at Petsmart and have just run my first batch of .308 cases in both drums that came out clean but still have the discoloration of the annealing at the neck of the brass.
Should I add some of the aluminum oxide to the drums I have for my media blaster out in the garage to remove this discoloration or just don't worry about it as they seem pretty clean?
As well, would you think removing the spent primers before tumbling should be done?
