The Acme 122 FP is more accurate than the RN in my CZs.
It may generally be, or not - - I don't know.
But I know my CZ pistols are responsive to tuning velocity in a way some of my other pistols don't seem to care. And I think sometimes we have a tendency to load to an arbitrary velocity, let's say to meet a preferred power factor, and we end up comparing two bullets at a particular velocity or particular power factor rather than two bullets at their optimum velocity or power factor.
I can tell you that my Shadowline seems to have an accuracy node with an average velocity between 1060 and 1080 with 124/125 grain bullets, regardless of type or profile. That's a PF range of 132-135, so perfect for 9mm minor competitive shooting, but 147gr bullets are most accurate in the PF range of 135-137, and 135gr bullets up around 137/138 PF.
One of these days, I will pick up some of those ACME 122, but I will have no expectations on where those accuracy nodes may be.
