Mar 31, 2021 · I’m really wanting to use the 245 Berger’s or the 250 A-Tips. Barrel length will be somewhere around 27-28” finished and was thinking of a twist rate of 1-7.5” to 1-8.5”. Berger’s twist rate calculator says I’ll be way good with the 1-8.5”. Just curious to see everyone’s experience and thoughts.

Try Berger's Twist Rate Calculator. You'll have to input some data about your bullet and conditions, but it should give you a good idea if the twist rate you were planning on getting is appropriate. You're looking to have the stability for your twist rate somewhere between 1.4/1.5 (barely stable) to 2.0 (starting to get overstable).

Form factors close to 1.0 are average. Bullets with form factors below 1.0 will have high BCs for their weight, and will perform better at long range. Minimum Twist: Minimum twist will enable you to shoot good groups but you may experience a compromise in ballistic coefficient (BC) performance. Use the Berger Twist Rate Calculator to determine ...

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 Berger Twist Rate calculator also uses the same term "Stability Factor" but abbreviates it "SG" rather than "s". It's certainly been very valuable to me: By spending a short amount of time gathering bullet specs, plugging them into my spreadsheet and solving the predictive stability factor calculation ...

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.Use Twist Rate Calculator. Classic Hunter Hybrid Features.

They may not be at the optimal BC. At sea level and freezing temp you need a lot more twist and that is where the ...The rate of twist is expressed as one turn in so many inches (i.e. 1 in 10" or 1:10). The caliber, length, shape and velocity of a bullet determine its optimum twist rate. The standard twist for a rifle barrel is designed to stabilize the range of bullets and velocities normally associates with that particular cartridge out to very long range.Look up the Greenhill Formula as a guide for optimum twist rate. A working calculator version is available here. Note that the formula includes the length ...

338 Lapua Magnum 300gr Elite Hunter Rifle Ammunition. Berger's hunting rifle ammunition is designed for effective expansion and hydrostatic shock for both short and long range shots on game. A “barrel twist rate” is referring to the rate of spin in the rifle barrel, indicated as inches per turn. For example, a 1:10″ twist rate means that the rifling will spin the bullet one revolution in ten inches. The lower the number, the faster the twist rate of the barrel. For example, a 1:9″ twist is a FASTER twist rate than a 1:10 ...Southwest Desert. Mar 1, 2016. #2. I shoot the 105 Hybrid in a 6BR with a 28" 1-8" twist barrel at 2935 fps, will put 5 in a 5" group at 1000 yds so I don't think you need a 1-7" twist.
