ARPC Energy Calculator accepts two basic parameters to calculate the muzzle energy of your air rifle. This is especially useful in countries such as the UK where muzzle energy is important to remain within firearms licencing laws.
Enter the pellet weight (grains) and the pellet velocity (fps) and the ARPC Energy Calculator will calculate the muzzle energy in ft/lbs (Ft.Lb).
