Not quite there yet.
Test load:
Powder: 24.5 grains TAC
Bullet: Hornady 75 gr BTHP
Primer: Wolf .223
Brass: Mixed (mostly LC)
COL: 2.260"
Average fps: 2644
Std Dev: 12.19
The primers look good, brass looks good except for chew marks on the rim from a sticky chamber. The last 15 shots or the chamber got really sticky. I hope it's not something in the powder. I wanted to make sure it wasn't something with my loads, so I loaded a mag of factory target ammo (Remington UMC) and it had the same thing. I tried to pull an unfired round of the UMC out of the chamber and could barely do it. I haven't had that happen before with my AR.
I'm going to give the chamber some attention tonight and load up some more rounds for tomorrow. If I can't get there with 25 grains or less, I'm thinking I might just cap it at 25 grains and call it done.
