Put it in the Berger twist calculator and the 1x10 gave me an SG of 2.1 while the 1x9 gave me a 2.6. All that’s needed is 1.5. Spinning thin jacketed Varmint bullets too fast can spin the jacket off or alter them enough to affect accuracy at range, so I went with 1x10. Longer, heavier 6mm bullets will get fed to the 26” 6mm Grrrr upper that will share the lower.
I wanted to get 1x8 but there were none left in the sub $100 barrels. Probably what I bought will be good. Thanks.
