I like 322 a lot, always have a jug handy. Pet in my 22BR. Meters GREAT. I've done 322 loads under 40s in 223, they were nice but my reality afield is, if I'm shooting 40s in a 22, I'm shooting "gopher loads" which stay a lot cooler over a session. In 204, I have had excellent luck with TAC, which burns a bit slower, in the old H-335 range without 335's warts. I'm just bringing this up because comparing 223 Rem to 204 Ruger, seems the Ruger does better with the "slowish" powders you'd use in 223 Rem. So I'd suggest trying the 322, then if you CAN, find a pound of TAC and try your luck there with the same bullet/case/primer.
