Leupold and Burris scope have worked fine for me as set and forget scopes. As long as they are babied, protected like a new born, put in swaddling clothes, I mean soft case, for extra cushioning in the rig, etc. Not thrown around or dropped or bounced around. Had one go 30 years never lost zero, babied on probably 20 hunts, that one just got retired for a Trijicon.
Only Trijicon complaint so far is limited ring spacing and more scope tube diameter in the wrong places for my existing mounting system. Had to use higher rings or go to a pic rail. Both 3x9x40 ish types.
