Calculate what barrel twist is needed for a stable projectile or decide what bullet is needed to shoot your bullet with stability in your existing twist. This uses a formula that is more accurate than Greenhill, and also considers atmospheric conditions. You may either set the current conditions, or use the default worst-case ones to ensure stability for universal use.
