Professor..
Like you, I got tired of media in cases, but I started with the sifting pan a year ago when I got started. I found it worked ok on pistol brass but still left media in rifle brass...I got tired of shaking the media out of rifle cases like a salt shaker..
The design like rcmodel has solves that nicely, like another poster mentioned I think dillon saw it as well and like the saying goes "imitation is the sincerest form of flattery" so I got the small cm 500.. it handles the load from my tumbler of 38 special brass, and I have used it for 45,9, 38, 223,6mm, 308, and 10 turns in one direction then 10 turns in the other direction all the media is separated.
Yes there are less expensive ways to do it, but I wanted to solve the problem forever.
This was the last tedious aspect of loading for me to solve.
The others were trimming, rifle case prep, and weighing of charges with powder that did not meter well...
Lots of diffrent ways to get there, but they all share one common element...
They require Opening the wallet....
I ended up with this to separate media
