I am shooting a Remington 7600 30-06 carbine with DNZ game reaper low mounts. I originally had a Nikon prostaff 2-7x32 on it and never had a problem. I recently mounted a Leupold vx3 1.75-6x32 on it and even with the scope adjusted as far up as it can go, I am still shooting about a foot low. Anyone know why?
