The black powder calculator provides the functions for estimating the muzzle velocity. The equations for estimation are a further development of the calculation bases presented by Don Miller in the magazine "Black Powder Cartridge News" #76 (2011, pp. 27-30). The GRT further development of the respective equations includes an adjustment of the factors on the basis of own measurements, including additional bullet variants and black powder varieties. * **Formula**\\ Here you select the equation to be used. * **Powder type**\\ Here you select the used black powder. * **Barrel length**\\ Enter the length of the barrel in inches here. * **Projectile weight**\\ Enter the bullet weight in grain here. * **Projectile type**\\ Select the projectile type used here. For example, it is also permissible to set a miniƩ bullet or a round bullet for a black powder cartridge. * **Powder charge**\\ Enter your powder charge in grain here. The calculation takes place automatically after changing a parameter. en/doku/bpcalculator.txt Last modified: 2021/05/30 03:34(external edit) Log In
