Multiply the weight of the pellet (in grains) times the square of the velocity and divide that number by 450436.7. If you are still reading this article, we assume you want to know the sheer mathematics behind the calculation method. This section of the article is for curious ones. Now, when you have the values, use our muzzle energy calculator below to determine the power of your air gun.

MUZZLE ENERGY CALCULATOR HOW TO

In case, if you don’t know how to do it, you can read our article about How To Measure Muzzle Velocity of A Gun. Please note that the muzzle velocity may not be exactly the same due to several factors, which is why we need an average value. Note down the readings and calculate the average value. Measure the muzzle velocity of your air gun using the ballistic chronograph with each pellet. Note down the grain of the pellets which are to be used for the experiment.

We recommend using RWS, JSB, Gamo air pellets, though you are free to choose your own pellets. High-quality pellets provide the most optimum consistency. Make sure you use branded high-quality pellets, not the locally made ones. Once you’re equipped with the above-mentioned instruments, you are ready to run your experiment. A ballistic chronograph (We used Wellshot IR Velocimeter to conduct our experiment).To measure your air gun’s power, here are the things you need. In imperial system, will be in unit foot-pound, will be in gram and will be in feet per second. The standard unit of above will be in unit joule if the mass,, is in kilogram, and the speed,, is in meter per second. For a constant velocity, if the mass is doubled, the energy is doubled however, for a constant mass, if the velocity is doubled, the muzzle energy increases four times. The velocity of the bullet is a more important determinant of muzzle energy. The general formula for the kinetic energy is:Īlthough 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. Muzzle energy is simply the kinetic energy of a projectile measured at the moment it exits the muzzle of a gun, which is when it is going fastest. The power of an air gun is known by its muzzle energy the measuring unit is Joules. Now, you can see the caliber of your air gun engraved on its barrel or stock, But the power is not written anywhere. So, it is always good to know the power of your air gun. And 20 Joules power without a proper license. Moreover, as per the Indian Arms Act, 1959 (Amendment 2016) it is illegal to own an air gun beyond. Sometimes there are mischievous sellers sell air guns by overstating its power. Even many expert shooters fail to tell the power of an air gun. Many times there are many misconceptions about the power of an air gun.

It’s always very exciting to own a powerful air gun. Many times, when we look for an air gun to buy, we look for its power.
