I ended up selling some extra .22lr ammo I had stockpiled before the craze. This got me some money to buy a tumbler, sifter, and brass polish. They arrived yesterday, and I did a test run with 20 pieces of brass I had already cut and formed. Everything seems to work well, so I'll be working on cutting and forming the majority of the .223 brass I have saved up. I'm keeping some to eventually reload .223, but I can get factory ammo cheap enough that I'm not gonna worry about reloading it any time soon.

The table setup I have works fairly well, except when I'm forming the new shoulder from cut .223 brass, the force I have to put on the lever moves the clamped wood off of my bench. I'll probably end up either having to put a screw into the bench, or figure out another way to clamp the press down. I need to figure it out before I really get going.
