I'm starting handloading .223 and I was wondering if any of you had SD load suggestions for a 11.5" 1/9 twist Armalite barrel. I think I would be better served with a 1/7 but it'll have to wait.
So far I've been using RUAG 63gr 5.56.

Sub-moa with my 4x TA31 at 100yrds. Haven't chrono'd it yet. Should I stay with it or try some heavier grain, I've been looking at Hornady 68gr BTHP, SMK BHPT 69 gr.
As for reliability, I know it can't compare with the field, but I've never had any malfunction on mine. (Shot close to 10k of rounds).
