That's doesn't tell us much. Very few people return scopes to the dealer that sold it to them when they go bad.
For another, a scope that fails within the first 40-60 rds. also doesn't tell us much. Any scope can do that. It simply means that it's bad from the factory not a less than rugged design.
That leaves us with those scopes that break down under recoil or those that move when impacted. So the question is how many rounds from what rifle(s) was it used on? Or just what did it take to get it to shift zero and how much ?
I've noted that Zeiss has apparently improvered the ruggedness of their Conquests. It seems they had a number of early failures when they first came out. But not any longer.
Swarovski is apparently not pushing their AV's for really hard kicking rifle use. But they do their PH models. Their latest scopes apparently use the PH erector design, not the AV design.
Zeiss now apparently does some sort of impact testing for their scopes at 1000 g's. But they don't mention how much or any of the other details of their impact testing. I have yet to see any sort of recoil or impact testing for the Swarovskis. E
