The Bcalc Recoil Calculator is an open-source firearm recoil calculator.
You can enter specific firearm and ammo data and the calculator will estimate:
- free recoil energy: total energy absorbed
- recoil velocity: speed the firearm moves backwards
- average impulse force: average force on hands/ shoulder
- perceived recoil score: to be used in recoil comparisons
An internet connection is not required once installed. No user data is transmitted.
