Optimal 270 WSM, 7 WSM or 300 WSM F-Class barrel specs

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
.270 Ackley improved 29 inch 1.250 dia. target barrel 7mm STW 28 inch 1.250 target barrel. I also love my .458 mag for varmints and the biggest game in the world.
