[QUOTE="ModernRedneck, post: 2056802, member: 83985"] So...I want to throw this out for everyone to chime in on. Based off your test from Rifleshooter.com, I pulled the muzzle velocity for an 18” barrel and loaded in the Barnes 120 grain data into Carbon Six’ Twist Rate Calculator. [B]See attachment for the recommended twist rate...[/B] Note (From the Carbon Six Site): "This Twist Calculator Calculator is a tool for determining the Gyroscopic Stability (GS) of your bullet and is based on the Don Miller twist rule. This calculator is used to find the optimal twist rate for your bullet. This is a general information calculator and there may be additional parameters that can have slight effects." According the trust rate calculator, it’s showing that a suggested twist of 8.8. So, if I will primarily be using this bullet, should I still go with an 1:8 twist or would 1:8.5 be better??? I know I know...folks keep saying 1:8...but wanted to double check after seeing this data. [/QUOTE]
