To separate the stainless steel pin tumbling media from the cartridge cases I've been using a RCBS Case Cleaner Media Sifter (looks like pan a prospector panning for placer gold would use) I set this pan onto a 3 gal plastic bucket that I've punched a string of ten 3/8" drain holes 3" below below the bucket top and about 1/3 of the buckets circumference.
I have the bucket in the laundry tub and dump the tumbler drum onto this pan on bucket set up.
The SS pins fall through the pans sieve to the bottom of the bucket. I flush out pins with running water from the short hose at the laundry tube faucet rinsing off the cases.
Water gets shook from the cases and rolled on a towel then put in the cloths drier on the stationary rack on low heat to dry internally.
Rinced and drained pins get spread out on a baking sheet and get dried on the rack in the drier.
I store the dried pins in a wide mouth plastic bottle.
I use to use a squirt on Dawn in the tumbler but it makes so much suds that are able to support pins and float them out the drain holes. So noe I use low sudsing dish washing machine detergent.

I use a sieve that I purschased from a wholesale kitchen supplier. It is 15" diameter, holds 5lb of ss pins and brass easily and fits in the kitchen sink. Yeah, a manual process to pick out the brass and ensure no ss pins remain in the brass while rinsing. They go on a towel to get blasted at take-off speed by my wife's hair blower (yes, I get the WTF-O look?) A magnet picks up any stray pins in the sink or elsewhere. Job Done.

I use the cheap Frankford separator that sits on a bucket. The trick is to have enough water in the bucket so part of the cases are submerged in water while turning it.

after the case won't go in the sizing die i generally dump them out all over the floor

I empty the cases wet, under water. I put the full tumbler in the sink and start running water in. I pull each case out (usually 4-5 at a time) and pour the water and pins out of each case back into the tumbler barrel. I dunk them in and out a few times. Doing it wet seems to keep the pins from sticking. Then I put them on a cookie rack and into the oven to dry. Once I pull them out, I check each one with a flashlight for any more pins. This process is easy, fast and effective. You just gotta watch out for pins crosswise with .25 caliber necks.

I use the same media separator I used to use dry, the crank type with a cover. I fill the bottom with water and grand for 20 seconds or so.

Then, I pour the water through an appropriately sized food strainer and I can then dump the pins back into the tumbler.
