Going to put a new barrel on my Christensen Arms Mesa chambered in .28 Nosler. Nothing wrong with my current barrel other than it's the factory 1-9 twist and I've developed a load that it really likes using Berger 195 EOL. Berger tech told me that the bullet will become unstable somewhere around the 700 yard mark, I can't remember the exact yardage but it was up there somewhere. Wondering if I should increase my barrel length, is there a benefit to a longer barrel, 28"-30", what manufacturers do you guys suggest, right now I'm leaning towards Brux
It's not about the length. It's twist rate. You should be running something in the 1:7.5-1:8 range for those 195's. Id drop the bullet weight down to the 175-180 range and use up that barrel. Next go round get tighter twist barrel and run the 195's.
