Calculate Muzzle Energy  
We don't yet have an automatic system so you'll need to grab your calculator.  

To calculate muzzle energy:

Velocity X Velocity X Bullet Weight  =  ft. lbs.
(velocity in feet per second, weight in grs.)
example:  a 115 grain bullet traveling at 1300 fps = 431 ft. lbs. of muzzle energy

* bullet weight should be on ammo box.  If velocity is not on box you may have to visit the manufacture's web site.
