I had a 3x9x40 on my 260 rem. never gave me a bit of trouble. I sold the 260 but kept the scope and put it on my muzzleloader. Still no issues whatsoever holding zero.
I'm not real picky about my optics. As long as they do their job to my expectations, I'm happy. I would say their at the "high end" of "low end" optics.
