N130 is pretty snappy for 50gr as it is and already gives decent case fill
the 5 series powders are higher energy rather than faster burn rate and of more use to larger case volumes
Watching this with interest now!
Rake Aboot will have a laugh as I'm now thinking of a .222 myself (as he accused me of being jealous because I hadn't got one). Anybody got a pointer for a rifle make for this calibre bearing in mind I want to keep it as light and handy as possible, my young son is showing an interest which is my excuse anyway!
Actually I have a pound on VV N-530 . I got it , the N-120 and N-130 originally for use in my 444 Marlin's with cast bullets .
All three have done okay or better in the 444 cast application . And the 120 and 130 have done nicely in the 222 . Makes me think I might try some of the 530 in my old 722 .
a specific charge of 530 should produce a pressure column similar to a lower charge of a faster powder but without the potential pressure spike associated with a faster burn rate.
I would start loading at N120 min levels and work up VERY slowly.
given the size of the case a 0.2gr increase can be dramatic and a "Go" or "No Go" situation!
its all going to be down to your rifle, brass and bullet combo anyway
be interested to see the results
