Energy Calculator

This tool will help you estimate the energy of your favorite cartridge. If you are unsure of which bullet weight and/or velocity to submit, use the information from our on-line ballistics tables above.

Example: The muzzle energy of a 300 Remington Ultra Mag 180gr Core-Lokt Ultra bullet propelled at 3250 feet per second is determined using the follow formula:
M x V2 ÷ 450400 = foot pounds energy.

Step 1: Multiply M (M = bullet weight in grains) times V2 (V2 = the square of bullet velocity in feet per second): 180 x 3250 x 3250 = 1,901,250,000

Step 2: Divide the product of step 1 by 450400: 1,901,250,000 ÷ 450400 = 4221 foot pounds of energy.
