Stonehenge,
Just curious. Why did you go with a 1x10 twist?
They are showing one in stock with a 1x9 twist right now with the same specs as your other barrel.

It will pretty much be for a dedicated p-dog popper and I’m going to focus on the 70s. 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. A p-dog at 600 is about a 1/2 x 1 MOA target (maybe a little more depending upon posture), so every little bit counts. A lot of people out there claim 1/2 to 3/4 MOA from BHW barrels, so hopefully flat based bullets can get me on the low end of that range. I have gotten well inside that with 110 varmageddons out of a stock 308 RPR barrel. Longer, heavier 6mm bullets will get fed to the 26” 6mm Grrrr upper that will share the lower.
