If that is the only powder you have, I would start by offering it up for trade for another powder better suited for .223. H4350 is very sought after and you could likely get a 2 to one trade as it is usually more expensive and harder to find than .223 powders. I would not load .223 with it though to answer your question.
Appreciate the answers, what is you guys preferable powder for this?
