VX-2 3-9 (in fairness this one lasted ~1000rds)If you don't mind sharing the scopes that failed?
I have Luke's old short barreled 358 on my montana, have a older bushnell elite 1.5x4.5x32 but haven't shot it alot. I don't want to have a issue with a scope...
Meopta 6x (x2) (~10 rounds, ~15 rounds)
Vortex Razor HD LH 1.5-8x32 (don’t recall rounds count. 100?)
Each was in lapped rings and properly torqued. When using those lightweight scopes the rifle only weighs 6lbs. It can be pretty snappy on recoil. Not a big push, but very quick.
