Recoil Calculator

Estimate recoil velocity, momentum, and energy so you can compare loads and fine-tune comfort.

Enter the ready-to-fire firearm weight in pounds, including the optic and accessories. Do not include the shooter.
Enter the projectile weight from your load data, in grains.
Enter the actual propellant charge weight for one cartridge, in grains.
Enter average projectile velocity from the firearm when available.
Estimated velocity of propellant gases leaving the muzzle. Leave the 4,700 fps default unless you have a better value for the cartridge model.
Free recoil resultFree recoil is a physics estimate for firearm movement without accounting for stock fit, recoil pads, gas systems, brakes, stance, or the shooter's perception.
Enter your firearm weight, projectile data, and velocity to see recoil energy.
