I went down to the range house on the Ranger and hauled up the consolidated buckets and a small work table and chair to the garage. I originally intended to work on the brass at the range house... but this is Oklahoma and there is no power at the range house, yet. I have a fan in the garage.

I don't mind sweating a little, but heat exhaustion is a little much to ask to sort brass.
I got all set up, and sat down to sort. I can tell you that the
Dillon Sorting Trays worked as well as I remembered. The top Yellow tray catches my 45 brass. The second Blue tray catches the 40 and 38 brass, and the Black bottom tray traps the 223 and 9mm. The key to success here is to do the sorting in smaller batches so that you can "pan" or shake the brass. Overloading the trays don't let them do their job. You actually end up taking MORE time because you are hand sorting that brass that didn't fall thru because YOU overloaded the trays.

In the above pic, you can see I have the three trays stacked in the proper order sitting in a bucket. The bucket catches the debris from the brass, as well as any stray 22 brass that might have gotten tossed in with the other brass. It also gives you a convenient working surface. I pour enough brass in to cover the bottom of the yellow tray, and a tad more... NO more than that. Then give it a shake. I shake until I can't see odd brass in the top tray. I pull the yellow tray and dump it on the table and inspect the brass. (Just me, you could dump it if you like.) I then toss that 45 brass in IT"S container.
I give the blue tray a few hard shakes, panning to make sure the 9mm and 223 falls thru. Then I dump that on the table and sort out everything not 40 caliber.

When picking through, pull the 38 and the stuck cases of 9mm. When you are down to just 40, scan one more time looking for oddball cases, just in case. (Pun Intended.)

You usually find a couple.

In the first bucket, it was mostly 40 caliber and just a few 45s and 38s, with a rare 223. I knocked that half size bucket out pretty quickly. I opened the next bucket and got started. Imagine my surprise, (NOT) when it was a different eclectic mix. This bucket leaned heavy on 45 and 38 and had very little 40. So I pulled the 40 and left the 38 for last. Whatever works. I stopped after the second bucket, since I had been using both hands, working that thumb that will need PT to get it's range of motion and strength back... just to pick up cases. NO lifting.
I can feel it now, but you have to work them or they stiffen up. Injuries, regardless.
