    I will soon have a new barrel installed on my 270 WSM and would like to know if anyone tried 270 WSM in F-Class competition.
    What would be the "optimal" configuration: barrel profile, length and twist.
    I'm planning to shoot Matrix Ballistics 165gr and 175gr Hunting VLDs.

    I want to be able to buy factory ammo and hate recoil so I'm going the way of the 270 WSM but might try a 300 WSM barrel if it's "better".

    Get the rule book out. I have or have owned 3 F class rifles. The max weight is what you have to work on. 22 pounds My 270 AI has a 9 twist for the heaviest .277 bullets made. The barrel is 29 inches amd 8.5 pound chromoly

    So 270 wsm is a wonderful choice. You will always be the underdog against the hoards of 6.5, 7 mm and 284 bases rifles

    So you add up your rifle without barrel on it and order accordingly My advice would be 9 twist and about 30 inches fluted stainless. with as heavy a barrel as needed.

    Heavy .277 are very low recoil just because of the shear weight and don't require an brake
