I started using N570 last year, when Retumbo went away, for 7RM. Works really well for me with 175 CorLokts. Tried it in 243AI with 105 Bergers and couldn't get enough velocity but it shot like a lazer. So I tried N560 and got all the speed I need with lazer accuracy and ES of 13 from 10 shots. I was amazed! Next up, my 300 Hamr, which really likes the N120 I fed it. Its a 150 yard gun, so ES doesn't matter much, but the ES of 15 over 5 shots made me smile. My 308 likes N540 with 168 SMKs, a lot! Gonna try N530 in 5.56 next.
Yes, I like VV powders! Their ES is amazing, they're very clean burning, and they're usually available somewhere online. Also, a competitive shooter friend tells me their lot-to-lot consistency is better than any other brand. Buy some!
