I have no idea of what I actually have as I purchased from a fellow forum member and don't recall specifics.
I'll be checking twist rate.
Here's what the seller quoted. I'm confident in the numbers.
Pac-Nor super match 1/10" twist
31" 6 groove
1.350" for 4" tapered to 1.25@7" and then taperedto 1" @ 31"
6 flutes.
Nothing but questions on this end...
