Any of you guys out there that are into being whipped on by a Nyati happen to know what twist rate you're running? I'm getting set up to grind the hook clearance for my first 585 reboring project (4 barrels) and the only thing I've found was the 1:20 that Seyfried used on his project. Sounds like reasonable accuracy, but thought I might gather some more info first.
Thanks for any info in advance.
