Yep, one of my first case cleaning attempts involved "pet bed" corn cob media and hours of digging out 223 cases.
Switched to crushed walnut and it works better save that if you deprime before you clean you have to check the primer hole to make sure it's not clogged.
I have the Franklin Rotary cleaner now and can use steel pins with water and soap etc. That route really makes them shinny and clean but is a pain if you don't have the big magnet designed to pick up the pins and a sink somewhere that you can make a mess. I usually only do the steel pins when I have a whole barrel full of 9mm. Most all else gets tumbled with the walnut shell media.
Life is good.

It was just that experience that caused my switch to The FART and pins. I started with corn cob, added walnut, even threw in some dry rice based on a recipe I picked up from YouTube. Didn’t matter....I still had to sit with a toothpick and poke out hundred of Primer holes...and I still had plenty of media inside my cases that fell out into the Berry’s boxes I use to sort and store clean brass. I’d imagine 223 is even worse since you can’t see inside the cases as easily.
However, I simply use my kitchen sink. No mess, no fuss. The few pins that fall in the sink are stopped by the strainer basket over the drain. Today I did 900 rounds of mixed 45/40/9 (won’t do that again) and didn’t even bother to pull out the magnet. I do have the Frankford Arsenal strainer and the Bucket with rotating media separator. Pour out 90% of water, refill and rinse. Repeat. Repeat again. Pour drum contents into FA strainer over bucket, rinse and stir to get 80% of pins to bottom of bucket. Transfer into FA media separator basket and spin inside water filled bucket. Pull apart nested shells, sort shells into repurposed frozen dinner microwave trays and dump pins into basket. Put towel inside strainer. Add 9mm, fold over towel, add 40S&W, fold over towel, add 45ACP, last fold.
Empty bucket into sink, preserving pins, pour residual water and pins into repurposed Planters Mixed Nut plastic jar which could hold 12-13 pounds of stainless pins so holds my 5lbs perfectly. Folded paper towels in the bottom of jar soaks up significant amount of water. Empty wet pins into heavy duty stainless frying pan...set to medium heat, stirring pins till dry. Brass spread onto stainless cookie sheets, set oven to 170 degrees. Heat for 10 minutes then allow to cool inside oven. Cool pins, pour back into dry nut jar. Recover brass when cool, store as necessary. Fin.
