Clockwise verses Anti-clockwise.

[Waisted]

Can the torque of a spring wether it is clockwise or anti-clockwise effect the pull or recoil of a spring airrifle?

[tinbum]

Yes, torsional recoil can be seen easily when using a scope. A top hat with slip washer helps counter this.

[robs5230]

+1 for that. Exactly as Nick says.
I always use a slip washer on the top hat and a power washer on the guide to minimise this.

Clockwise twist for Northern hemisphere shooters, anti-clockwise for Southern.

Old Walther LGV Spezials are used on the Equator.

What if the piston spins like AA do.

From a physics perspective, only pistons that are free to rotate should produce any rotation of the action - otherwise you have not conserved angular momentum.

Why not put the spring in the other way around

The old BSA Standards used to use two springs wound in opposite directions presumably to counter this when bell target shooting. Please correct me if i'm wrong.

Thanks to all those who replied, so a badly cut ill fitting spring with no washes could cause pull either left or right depending on the rotation of the spring.

Yes

Because it would be exactly the same unless you manage to turn it inside out

As long as the piston is freely rotating, then yes. It should not be possible on a non-rotating piston with a cocking slot, e.g. HW type.

I think the biggest cause of this type of effect is actually the fit of the rifle in your shoulder, causing the rifle to deflect and rotate during recoil. I have yet to find a gun that actually does it, but I bet shooting from the other shoulder would reverse the effect.

I know, hence the grin.
