As for the Whiscombe, if you want to analyse bending due to moment it's actually happening in both the vertical and horizontal planes (vertical due to what you said above) and horizontal as the gear is offset from the center of the piston/springs (it's below it), hence force is applied away from the place where the load is being held, bending the cylinder.

If we go into that much detail, maybe you'd expect airguns to be 100% efficient too, or anything less is not perfect...

Please define perfect
I put 5 shots into a 5p piece target at Cobham club's 100m range back in 2006. Thats fingernail group at 100m. With a springer.
As close to perfection as anything yet done.
