Springers are actually far more likely to break a scope than any CF rifle, the reason is that a CF rifle has a "one way" recoil, whereas a springer has a "recoil" that moves both back and forwards, also vibration can kill a lesser scope

The Eliminator mounts run on rubber cored "Dampa mount" system, so does the Dual Magnum which although still "recoils" the rubber takes away vibration, if the BSA Supersport was "piston slamming" (which is quite likely as they dont have the best of piston seals) then it isnt surprising it was a scope eater, notice the same action but on the Lightning series has a scope rail that sits on a bed of rubber, which solves the problem

I have a WTC model like the one mentioned on a HW80 running at 20ftlb, been on it for years, it has smooth firing cycle so no problem

A lot of scope makers test models on Magnum springers, to declare them as Springer rated
