For those shooters who may not yet know and in memory of the great shooter who gave me this formula 35 years ago here is how to calculate muzzle energy:
<br>
<br>ME=(V2/7000)/64.32 x bullet weight in grains.
<br>
<br>IE My old .44 Mag service load (in the days when carrying handloads wasn't antisocial for law officers) sent a 250 grain Keith bullet out of the 4" barrel Model 629 right a 1000 fps with a resulting ME of 555 ft lbs.
<br>
<br>1000 x 1000 = 1,000,000 / 7000 = 142.85714 / 64.32 = 2.2210 etc. x 250 = 555.
<br>
<br>FYI, Good shooting!!
