re-barrleing Tikka .270wsm
I am finally getting to re-barrel my Tikka, and i will be loading some Matrix 165gr .277's. What twist for the heavy bullets. Right now I am shooting 140's in a 1in 10, I was wondering if 1-8 would be better. Am thinking of a 4 groove. Thoughts?
Will have the chance to shoot whistle pigs out past 600 here in Pa
