Lyman Turbo Media Sifter
I dump mine into a Lyman Turbo Media Sifter. This item can be found at
www.MidwayUSA.com right now, the price on this item is $9.99 and is currently available.
I have reloaded over 30 years.
The 'trick' is to not only shake the cases/media but to have a large-enough sifter so you can kind of shake in such a way so as to shake in a vertical-rolling type fashion which lets the media and cases kind of roll over themselves, over and over. I shake over a sheetrock pail which is large enough to not spill any media anywhere but into the pail.
I find the movement is kind of a circular motion to and from my person, shaking sufficiently to the point of almost overflowing over the edge of the sifter tray. As you progress and drop the majority of media into the pail below, you should now see the cases turning themselves over and over. As you get to the bottom (majority of media now sifted out of the sifter), you can then be more aggressive in your 'tossing' the cases and whatever media is still visible in the sifter.
When the shaking is done properly, it only takes a few minutes. The shaking needs to be done in such a way so as to not overflow media over the top of the sifting tray.
I suppose I could mount that tray onto the vibrating tumbler center spindle shaft so the tumbler actually does the final shaking to remove media from the cases, automatically-dumping the media into the tumbler's bucket.
I have never tried that but just thought of it while typing this.
I'm sure, with the majority of media in the tumbler's bucket (media needs to be in a vibratory tumbler in order for the thing to have enough weight to properly vibrate), the final vibration-method would work well at shaking the media from the cases. I don't have any cases to tumble right now that need tumbling and sifting so I shall remember this the next time I tumble.
When done properly, the only media I deal with after tumbling is an occasional tiny piece being lodged in the cases' flash hole. Those need a sharp pick to pop out of the primer pocket. Since I quickly rub the media dust from the cases with a small rag and am typically ready to clean the primer pockets, this is the stage at which I pick any pieces from the flash holes.
