The conservation of energy principle is fully at play here, meaning what goes forward has an equal amount of go back push too.... but there is a big difference in the two, and there are a number of devices employed to minimise the impact on the shooter.Originally Posted by Sniper
- The mass of the rifle slows the impact considerably
- Size of the butt spreads the load
- Any energy used in cycling the weapon removes some of the energy from the overall felt recoil - and possibly the projectiles travel
- Gas vents put on the front of the barrel the deflect any of the gases back/sideways
Additionally, an air rifle often has a reverse recoil.
That is after the initial push against the shoulder while the spring and piston accelerate forward, moving the column of air and projectile with it, there is actually a considerable "pull" the shooter will feel that happens as a result of the piston hitting the stop and the end of it's cylinder. Of course it happens very fast so it's not easy to discern the individual components.
For this very reason air rifles need to have scopes of a different construction, and often need different mounting mnechanisms and they'll creep backwards along the dovetail (every shot the rifle jumps forward, and the inertia of the scope "drags" it back.
Simple really... and when it comes down to it - I'd rather be on the blunt end than the sharp end receiving the energy...
