I always tend to think of H-380 as a 22-250 only powder. If you look at the website, it works in about anything Varget or BLC2 uses. .308, .300 or .250 Savage .243. I suspect it's a little slow for .223.I switched from H380 to IMR8208xbr. That leaves me with a couple of 8 lbers to do something with.
Anyway, I started with H-380 and 50 grain Nosler BT's. First group was one hole. It should work as well or better with 55's. I'd use it because I got 4# at a close-out for $10/#
