I put a Bushnell pistol scope....
on a 12 ga shotgun slug barrel.
The scope is a Magnum Phantom, circa the 1970's. I understood it was designed to withstand the recoil of the 44 Magnum pistol. So far, with about 100 rounds of 12 ga slug fired, the scope holds the zero and nothing has broken.
Two of my rifle scopes are Leupolds, and the third is an expensive ($700 MSRP) Pentax Lightseeker.
While the Leupolds were half the price of the Pentax, they seem to be every bit as good.
None of my scopes have broken, yet.
Artillery lends dignity to what would otherwise be but a vulgar brawl.
