After using the old walnut shaker and Sonic cleaner for the past 3 years I decided to try the SS tumbler method to see If I could get my brass cleaner but mainly the primer pockets. Well, after following the tips and tricks I found here I went ahead and tried it and am not that impressed with the results. Yes, the brass came out really "like-new" brass but the pockets were just so-so. Maybe I tried doing too many at once(about 300 .223 pieces) in a F.A.R.T tumbler with 5lbs SS, Lemi-Shine, and Dawn for about 2.5hrs. Even if the pockets would have come out nice, the process of rinsing, separating, rinsing again and then drying seem to be a bigger hassle than it's worth.
