Has anybody else had a Leupold scope crap out from being pounded on large magnum rifles? I put a Vari-X II on my 338-378 this spring, and after about 80 rounds, it wouldn't keep it's zero. I sent it away, and Leupold sent me a brand new one. When I was up at the range today this scope did the same thing - it has had about 100 rounds on it. I just ordered a Bushnell Elite 4200, which claims to have been tested to 10,000 rounds on a 375 H&H.
