is very enlightening
the evaluator does a test where he drops scoped rifles first 18 inches onto a foam pad and then checks zero, he moves on to 3 foot drops onto the foam pad
the 3 foot drops might be a bit much, but 1.5 feet onto a foam pad should be nothing
spoiler alert: almost all scopes, even high dollar ones, easily lose zero
it's so bad it is almost depressing....scope makers (like phone and computer and software makers) seem to be focusing on looks and features and not functionality and dependability
the leupold i bought did horrible on this test....i'm going to bumped it around this spring and see if it holds zero....if not i'll be getting 1 of the 2 brands that held zero in those tests (night force or trijicon)
