[QUOTE="AZShooter, post: 1701462, member: 5219"] Your 9.5 twist rate is marginal for some bullets heavier than 160 gr. You can use Berger's twist rate calculator to see the stability of any heavy bullet that interests you. Bullet length is one of the critical inputs. Nosler lists the length of their bullets as does Berger. If you go to this link you can input the conditions and bullet to see how stable it will be for your rifle. [URL]https://bergerbullets.com/twist-rate-calculator/[/URL] I chose 35 degrees for input as you will be elk hunting. A few examples the 175 Nosler partition @ 2900 fps is stable even at 0 elevation and 35 degrees. While the 175 Berger elite hunter @ 2900 fps with its longer length is not stable until 4200 elevation. The 175 LR accubond at 2900 fps will be stable at 4700 ft elevation. The 180 Berger at 2900 fps is right on the cusp of being stable at 4000 ft. [/QUOTE]
