Generally speaking, most mortgage refinance calculators perfor...They leave about 3000 fps from 308 cases spinning fast enough to stabilize nicely. The Brits were first to do that back in the 1960's when their fullbore long range target rifles switched from 303 Brit to 7.62 NATO shooting M80 arsenal ammo with 147 gr bullets. 1:13 twist worked better in cool temperatures.

The twist rate calculator will assist you in determining the stability of a bullet when fired from a particular rifled barrel. It has been long-established that in order for a bullet to travel long distances while maintaining stability, the bullet should spin or rotate along the longitudinal axis.

The environmental lapse rate is found by dividing the change in temperature by the change in altitude. The environmental lapse rate is calculated in terms of a stationary atmosphere and may also be referred to as the temperature gradient.

FWIW - Berger's twist rate calculator by is set by default at 59 degrees F, 0 ft elevation. These are very conservative default settings. Unless you're planning on shooting at the beach in San Diego in January, use the elevation and approximate average temperature where you shoot most often as inputs.

For example the 215 Berger, .308 diameter, has a length of 1.60 inches. My Miller stability estimator comes up with a Sg of 1.19 (11 twist, sea level, 59*). The Berger stability calculator comes up with an equal Sg, 1.19. All this indicates the 215 flying out of an 11 twist may not optimize the ballistic capabilities of the bullet (BC).You can use the Berger Twist Rate Stability Calculator to determine the optimal barrel twist rate based on your specific shooting conditions and the bullet you plan to use.

Like .22 cal JSB 18.13s at 990fps on a 17.7:1 twist …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).

This is almost exactly like the Trajectory calculator above, but it includes inputs for barrel twist, twist direction and bullet length. These values are used to calculate spin drift using an approximation developed by Bryan Litz and published in his book, Applied Ballistics for Long Range Shooting. The stability factor is calculated using the ...Calculate population growth rate by dividing the change in population by the initial population, multiplying it by 100, and then dividing it by the number of years over which that change took place.

To calculate bullet stability, simply enter your bullet data (along with observed Muzzle Velocity, outside Temperature, and Altitude) and click “Calculate SG”. Try different twist rate numbers (and recalculate) until you get an SG value of 1.4 (or higher). Berger’s Twist Rate Calculator provides a predicted stability value called “SG ...What does SG mean? SG is the specific gravity, or the measure of gyroscopic stability applied to the bullet by spin. Mathematically SG is the ratio of the stabilizing influences of rotating mass, vs. the de-stabilizing effects of aerodynamics. If this ratio is greater than 1.000, it means the bullet has more stabilizing influence than de ...Using the Berger twist rate stability link they show their 175 as marginally stable.

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.

I use Berger’s twist rate calculator to figure the best twist rates for bullets that I intend to use and try to plan accordingly. With that being said I have run bullets that according to the calculator are marginally stable. The only issue that I have noticed was that the BC seems to be affected, I use a magnetospeed to collect velocity data ...

The Berger twist rate calculator shows that CE 130 gr bullet with an 8.4 twist starts dropping below the desired minimum 1.5 stability factor at an altitude of 3000 ft. An 8 twist maintains 1.5 or above down to 300 ft and a 7.5 twist is 1.68 at sea level.
