Berger’s Twist Rate Calculator gives a predicted stability value, called “SG” (for “Gyroscopic Sability”). This is the Gyroscopic Stability applied on the bullet by spinning. This number is calculated from the basic equation: (rigidity and spinning mass)/ (overturning aerodynamic force). Your bullet will not stabilize if your SG is ...Using "generic" temp/elevation inputs that represent our average shooting conditions here in SD, the Berger calculator predicts that 6.8-twist is the minimal twist requirement to reach an Sg of 1.5 for pointed 90 VLDs traveling at 2850 fps (below). The temp/elevation at your location, as well as your MV, will cause that required twist rate to go up or down relative to how much they differ from ...Gyroscopic Stability (SG) and Twist Rate. Berger’s Twist Rate Calculator provides a predicted stability value called “SG” (for “Gyroscopic Stability”). This indicates the Gyroscopic Stability applied to the bullet by spin. This number is derived from the basic equation: SG = (rigidity of the spinning mass)/ (overturning aerodynamic ...i have a custom rifle with a 25" barrel with about another 1" long brake on it. i measured from where it starts up against the action. it is a 1:9" twist. i have reloaded before for 308 and 6.5 cm and 6.5 saum. this is my first belted magnum.. i will be using it to hunt elk (cow elk)...

338 Caliber 300 Grain Elite Hunter Rifle Bullet. G7 BC: 0.417. G1 BC: 0.814. Berger's hunting rifle bullets are designed for effective expansion and hydrostatic shock for both short and long range shots on game.The Berger calculator requires at least a 8.5 twist (vs the 1:10 on the box) to even come close to marginal stability. Curious what experiences are out there regarding Hornady's twist rate requirements on the box vs real life experience. Seems Berger and my anecdotal experience would disagree with big H.Step 1—Finding D 2 : .244 x .244 = .05953. Step 2—Finding C x D 2 : 150 x .05953 = 8.9295. Step 3—Divide result by bullet length: 8.9295 ÷ 1.075 = 8.306. Rounded, 1:8-inch twist is Greenhill’s indicated twist rate for 80-grain bullets. As shooters have discovered, the reality is that a 1:8-inch twist can be marginal for a .223 Rem. 80 ...Berger Twist-Rate Stability Calculator On the Berger Bullets website you’ll find a handy Twist-Rate Stability Calculator that predicts your gyroscopic stability factor (SG) based on mulitiple variables: velocity, bullet length, bullet weight, barrel twist rate, ambient temperature, and altitude.

The Miller twist rule is better than the Greenhill rifling formula when measuring the specific gravity (SG) of a boat tail bullet because the Greenhill formula was originally developed for football shaped projectiles at subsonic speeds and is quite inaccurate for modern bullets.The Miller formula can calculate stability much more accurately for modern long range bullets.We’re happy to publish a major upgrade to our Twist Rate Stability Calculator which is available for free upon the Berger Bullets online.

Feb 7, 2018 · Berger’s Twist Rate Calculator provides a predicted stability value called “SG” (for “Gyroscopic Stability”). This indicates the Gyroscopic Stability applied to the bullet by spin. This number is derived from the basic equation: SG = (rigidity of the spinning mass)/(overturning aerodynamic torque). Berger twist rate calculator. Posted By: Mule Deer Re: Twist question - 05/22/20. It won't at 3600+ even at 4000 feet above sea level in my part of Montana. Oh, it'll land point-on, but it won't group very well. Have gotten much better accuracy with the 60 Partition in faster twists, including 1-8. If I recall correctly, it was originally ...

This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. It will a produce a line graph showing the bullet drop and flight path of the bullet. By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side.A perfect example includes the classic .223 Remington, 5.56x45 NATO, or .223 Wylde-chambered barrel designs. While 1:7 twist is the “mil-spec” standard, most manufacturers planning on optimizing their twist rate for a wide range of commercial bullet designs will gravitate toward a .223 Wylde chamber with a 1:8 twist rate.Hornady® Reloading App. Like the bound and eBook versions, the Hornady® Reloading App provides all the information needed to successfully reload a variety of rifle and handgun cartridges.
