Bullet Impact Energy Calculator

Like the bound and ebook versions the hornady reloading app provides all the information needed to successfully reload a variety of rifle and handgun cartridges.

Bullet impact energy calculator.

Muzzle energy isn t something that can be measured with radar guns or impact targets. You may add items to the list on the right in order to create a bar graph comparing the different items. Click here to open in small window. Plus you can save favorites add notes and more.

For example it can be used to calculate the impact force of a vehicle car truck train plane football of birds hitting a plane or wind mill as well as for falling bodies that crash into the ground. The general formula for the kinetic energy is where v is the velocity of the bullet m is the mass of the bullet. Bullet kinetic energy calculator. We use this nifty bullet energy calculator when we chronograph projectiles.

It s a velocity of about 20 m s. Bullet energy calculator. Three ways to get the hornady handbook of cartridge reloading. Well it will still hurt when it impacts a body but it definitely won t cause anything worse than a bruise.

Just enter your bullet weight below and its velocity. Enter the first two variables then press calculate. Muzzle energy will be higher when bullet is heavier and moves out faster from the muzzle. Muzzle energy will be rounded to the nearest whole number.

Using the impact force calculator. Calculate the energy the bullet will deliver to the target on impact using the formula ke frac w bv 2 450 437 in words the bullet energy ke in foot pounds is equal to the bullet weight in grains w b times the square of the bullet velocity v in feet per minute divided by 450 437. We thought you might enjoy it as well. This versatile impact force calculator is useful for estimating the impact forces involved in collisions of different kinds.

The velocity of the bullet is a more important determinant of muzzle energy. Instead it is a rather ethereal figure that can only be computed using the previously mentioned formula. It is calculated from mass velocity and weight of the bullet. In order to determine the kinetic energy you must know the velocity of the bullet and the weight of the bullet in grains.

Use the kinetic energy calculator to find out how fast that the same bullet will have to be traveling at to get its energy to 1 j. 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. Because velocity has such a huge impact on muzzle energy anything that affects velocity also affects energy exponentially. Muzzle energy is the kinetic energy of the bullet when expelled out from the muzzle to the target.

Use this online calculator and find the muzzle energy in foot pounds and joules. Reloading data is available as low as 99 per cartridge or purchase a subscription and.
