Pellet Weights And Energy Calculator

Let s find the velocity of an 8 grain pellet that generates 11 37 foot pounds of energy.

Pellet weights and energy calculator.

That would be 11 37 times 450240 and divide that number by 8. After the pellet leaves the barrel wind resistance starts to slow its speed. Weights and muzzle velocities for example energy calculations were approximate for general comparison only. Obtain multiple velocities from different gun settings or any other combination you want to compare with our fpe calculator to calculate muzzle energy.

This page was the most popular page so i have left it available online for historical reference. Calculated from retained velocity at two distances. Muzzle energy will be higher when bullet is heavier and moves out faster from the muzzle. Find the velocity feet per second of the exiting pellet.

Velocity from muzzle energy. In order to determine the kinetic energy you must know the velocity of the bullet and the weight of the bullet in grains. The square root of that number is your velocity. Bullet kinetic energy calculator.

Then hit the square root key on your calculator. Pellets are generally wasp waisted cylinders made of lead or non lead alloys and provide the highest accuracy in the rifled barrels of adult precision air rifles and air pistols. Pellets of various calibers are available in flat nose round nose pointed and hollow point configurations. Simple add the speed and grains into each of the boxes for each column.

Find the foot pounts of energy of the exiting pellet. Feet per second fps ballistic coefficient. I have moved on to other hobbies. It is calculated from mass velocity and weight of the bullet.

It may be inaccurate. Use this online calculator and find the muzzle energy in foot pounds and joules. Take the energy times the constant 450240 and divide by the weight of the pellet in grains. It may be out of date.

Pellet weights and energy calculator as of 2004 this website has not been maintained. This airgun energy calculator is a simple widget designed to take the velocity of a projectile bb pellet dart or bullet its weight in grains and calculate the foot pounds of energy fpe at the muzzle. You may add items to the list on the right in order to create a bar graph comparing the different items. Use the calculator below to calculate the kinetic energy of a bullet.
