Web2 feb. 2024 · Well we can calculate the effect of variation of bullet weight on muzzle velocity and measure it experimentally. Calculations with the internal ballistics code show that the fractional change in muzzle velocity for a given fractional change in bullet weight can be calculated from. (\delta V/V) = 0.24 * (\delta W/W) (δV /V) = 0.24∗ (δW /W ... Web10 dec. 2024 · Another way to look at this is you have to use more powder to achieve the same pressure and velocity when the bullet is seated out long. In fact, the extra powder you can add to a cartridge with the bullet seated long will allow you to achieve greater velocity at the same pressure than a cartridge with a bullet seated short. http://genitron.com/Articles/post/adjusting-muzzle-velocity-for-barrel-length thorens mm-05
