Best Muzzle Velocity Formula
You can determine muzzle velocity by using the kinematics equation.
Muzzle velocity formula. That last number is a constant created by multiplying two times the acceleration of gravity by 7000 - the number of grains in a pound. If you still need to know how to go about calculating the velocity you are in the right place. Multiply the product of the weight of the pellet in grains times the square of the velocity and divide that number by 450240.
Powleys modified formula relying solely. And v is velocity. Muzzle velocity and energy are usually stamped on the ammo packaging.
Powleys full formula using a normalizing constant of 8000. A low number indicates most numbers are close to the average. Muzzle Velocity Formula How To Calculate Muzzle Velocity.
The exponential profile works pretty well for modern rifles though not at well. Muzzle velocity changes to an estimated amount of fps. A 101 inch barrel gives 462fps.
450240 velocity in feet per second weight in grs. Muzzle Velocity Approximation Formulas Genitron. Drop AX - G exp 2 Q X- 2 Q X - 1 4 Q2 VZ2 where A is the tangent of the barrel angle.
Velocity X Velocity X Bullet Weight ft. Although both mass and velocity contribute to the muzzle energy the muzzle energy is proportional to the mass while proportional to the square of the velocity. Vo the original muzzle velocity fts B the bullet weight gr C the charge weight gr Lc the cartridge overall length in.
