barrel for Berger 55 grain 20 cal bullets

Who can or will make 204 caliber barrels with 8 twist or faster for the new 55 grain 20 caliber bullet by Berger?

I'm having great results with a 9 twist and the Berger 55s in a 20br. And I have read of someone having good results with a .204 Ruger and a 9 twist with the same bullet.

malcarjeb,

What load and what kind of velocity did you use and get?

I tried several powders with velocities from 3500-3800fps. They all were good. I settled on IMR 4007ssc at 3650fps. Its very accurate out to 500 yards.
