You can slam Leupolds all you want but I have an old Vari-X III that I've had on my Sako for ten years. A couple of years ago I slid off of a ATV bridge on my lease into a freezing cold creek. Threw me about 10-15 feet down the creek with my rifle right beside me. Cleaned the rifle and shot it that afternoon. Still right on the money. This scope hasn't lost any clarity in ten years. I like Bushnells also, but for my "go to" rifle I would only use the Leupold's VIII if it is anything like the Vari X III.
SO on my first elk hunt I took a Swarovski 1.5-6x42(30mm) on a 7 Rem mag and slipped on some rocks and the fell on the gun. DInged the objective bell pretty well , gun never lost zero. Same hunt fellow with a Vari-x III 2.5-8x36 banged up his scope and the glass in the objective shattered. VX-III's are not anywhere what a Vari-x III was except in price. They have a 3 piece tube not 1 piece like the Old vari-x III's. SO whats your point ? Are Leupolds rugged ..answer is yes are they the best and the answer is no.
