I've been hammering a VXR 2-7 atop a Steyr carbine for a while now. Rifles 8#, pushing a 270 gr over 62 g imr4895 to 2510.
So recoil is certainly present.
The scope has not shifted a click. Bases are Maxima's and rings are qrw.
My 270WBY wears a 4-12 varix and has never had any issues, but its shot much much less frequently that the Steyr. Still, its been going since 81.
A scope is a fragile thing compared to what its strapped onto. Over time, temperature changes and miniature high pressure explosions underneath it, something's going to weaken.
Buy right, mount correctly, don't abuse. I'd expect 25 years from a newly manufactured scope.
Products just are not made to last as long as they once were.
Some of those B&L scopes are still running as strong as the day they were unboxed.
