I had a 284 Win with a 10 twist PacNor. It would stabilize bullets up to the 162 Hornady just fine. Never tried anything heavier.
At the increased velocities of the Mashburn I would have zero doubt that the 10 would work, splendidly.
Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!
Yeah, it's a 700 but my first rifle, took all my first animals with it. I might have a hard time tweaking it like that. Besides, I could always use another. That way i'll have small, medium and large (7x57, 7RM and 7 Mash).
Wanted: Vintage Remington or Winchester hats, patches, shirts. PM me if you have something.
