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.

Bullet kinetic energy calculator. Muzzle energy will be rounded to the nearest whole number. Reloading data is available as low as 99 per cartridge or purchase a subscription and. Three ways to get the hornady handbook of cartridge reloading.

We use this nifty bullet energy calculator when we chronograph projectiles. 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. 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. Using the impact force calculator.

It s a velocity of about 20 m s. Use the calculator below to calculate the kinetic energy of a bullet. You may add items to the list on the right in order to create a bar graph comparing the different items. We thought you might enjoy it as well.

Muzzle energy isn t something that can be measured with radar guns or impact targets. Enter the first two variables then press calculate. Bullet energy calculator. Muzzle energy is the kinetic energy of the bullet when expelled out from the muzzle to the target.

Well it will still hurt when it impacts a body but it definitely won t cause anything worse than a bruise. Plus you can save favorites add notes and more. This calculator will display the foot pounds of energy and help you compare the power of different loads. Have you ever wanted to compare a fast lightweight bullet to a slower heavy bullet to see which one hits harder.

Muzzle energy will be higher when bullet is heavier and moves out faster from the muzzle. In order to determine the kinetic energy you must know the velocity of the bullet and the weight of the bullet in grains. Because velocity has such a huge impact on muzzle energy anything that affects velocity also affects energy exponentially. 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.

Just enter your bullet weight below and its velocity. The general formula for the kinetic energy is where v is the velocity of the bullet m is the mass of the bullet. The velocity of the bullet is a more important determinant of muzzle energy. 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.
