I've had three Leupolds and a Denver Redfield fail. Two Leupies quit at the range and one on an elk hunt. The Redfield turned toes up at the range. I'd just put it on a .35 Whelen. When I dry fire the rifle, the reticle makes a nice high jump.
The most expensive scope I ever bought was a 2.5x10 Minox I got a sweet deal on. The scope was NIB and you could adjust the elevation just fine but not the windage. Sent it back to the factory for repair and got it back in about two weeks. The adjustments work just fine now.
