I use VV-160 in my 6.5x284 Norma. It's the best powder for accuracy in my gun using 140 grain bullets.
Don't look there for N570 they don't have any.....
N340 4.9g with 124g jhp or fmj reg small pistol primer.since i've started reloading i've used and still use vitahuori powders exclusively. VV340 ,VV320,3N37 for .40 and 9mm. very clean and consistant jug to jug ,not temp sensitive and generally the powder bar meters well with vit powders.
can't wait to get a hand on VV310 for my 9's . very fast i know but i found a crazy flat shooting load 22 alike wiith that one.
