I have a Browning X-Bolt Hell's Canyon Max Long Range in 30 Nosler. Twist rate is 1 in 11. From my experience it shoots pretty dang well! I've hit a Steel Ram Target at 600yds with it consistently. Not sure of how tight the group was (the ram is on a public Range and needs a new paint job). I'm about to start reloading for my 30 Nosler! Been contemplating seeing if I can get a bigger box mag made bt Wyatt's installed so I can run higher Ballistic Coefficient on the reloads. And I'm also eventually thinking about running a 1 in 9 twist barrel on it so I have more bullet options to shoot like the Berger 215 Hybrid. Any thoughts? Or just leave it as is and see what I can do?
