I only run Leupold scopes and have had no issues except for a VXIII 2.5-8×36 that I bought from a friend who had dumped his rifle on ice and broke the elevation turret. It was replaced, but a spring was faulty and the group would shift slightly. The warranty depot is 30 miles down the road. The spring was replaced.
I have VX3 2.5-8x36 on a 6lb Kimber Montana 300WSM. I've taken that rifle to Africa twice and had no issues with the scope. Except for a Redfield Golden 5star on my slug barrel, all my scopes are Leupold, mostly VXIII or VX3, some VX2. Total confidence, but then I'm not a turret twister.
