VV530.
In a .223, it is quite close to H-4895. I used it with some old JLK 60-grain LD (the flat base ones) last winter in the Rockingham winter league for the Factory Class at 200 yards. It shot quite well, equaling 4895 with 62-grain Bergers.
Roy Darnell reported he tried it with a .30 BR. Said it was quite accurate in his rifle, but he couldn't get the velocity.
It probably is too slow for optimal use in a 6 PPC, and if you're going to compete, anything less than optimal won't work. But you might find it quite useful in the .223.
FWIW
