I always had excellent results from N133 under 52 and 53gn match bullets (Hornady and Sierra) when I loaded a slow-twist 223 many, many years ago. I doubt if there's much if anything that would be better across the board even today and N133 also has the advantage of widespread and reliable availability and reasonable pricing.
The much more recently available Reload Swiss RS-40 would almost certainly produce higher MVs, but this is a 'hot' number.

I use the following with the Sierra 52gr HPBT in .223.
Lapua brass
27.5gr of Hodgdon CFE223
CCI small rifle primer
COL 2.225"
I'm not sure of velocity but this load is nearish the Hodgdon max for this bullet (28.0gr). I had tried to test it but my old chrony wouldn't read them, and I only got a new one a week before lockdown...
Accuracy is about 3/4" at 100m from my heavy barrelled Browning X-Bolt but where I shoot is quite windy, so I'd like to think it would be a bit better on a calm day.
