I've got a Nikon on it currently, but I'll be swapping out my newest Zeiss, one of the HD5's. Eye relief is constant at 3.5" whereas the Nikon gets shorter as you zoom. The drawback of the No.1's is even at the furthest back on a typical scope, the scope is still much further away from you than on a normal bolt action. Hoping the Zeiss' longer eye relief at full zoom will cure this. Will let you know.
