sorry to take so long to get back, if you have questions on your scope, just swap it for another. you can answer the million dollar question that way. if it matters I scrambled a burris, leuy, swaro and nikon on my light RUM. the 4200 and the zeiss were the two I had success with, but I sold the gun because I could not trust it. the wretched thing would blow up the bedding in 200rds. those quality scopes are all good, but when you get into insane recoil velocities.......things change.
