2 years ago I was using the Omega on a 12 ga. Slug gun and after 15 rounds through the gun it started to shoot inconsistantly. I ended up sending the scope back to Nikon and they said something in the elevation turret had broken loose. They replaced the scope, and I had the same thing happen again. They replaced the scope a second time, but this time I put the scope on my Muzzleloader, and put a Leupold VXlll on the Slug gun and I have not had any problems. The optics on the Nikons are nice but the Leupold and Zeiss scopes seem to hold up to recoil better.
