Never had a issue with a Leupold scope in nearly 40 years. They've been the middle of the road I guess compared to the high end German scopes for me - and these are worth every penny.
Doing a BGR comp quite a while back now (read suckered into this) an ol' mate gave me a lap at his 500A&M on a Ruger No1 action.
The recoil was bloody horrendous to say the least, known for sailing close to the wind "Lumpa's" loads were HOT! When asked about that little scope, he'd never had it lose its zero - and it did 2 comps that day, straight after each other! And all his rifles get heavily used!
Even have a 2x7 on my 404 - no issues here!
So if you want dependability & reliability I can certainly vouch for them too.
