I mounted a Leupold Rimfire Scope on my Ruger 77/22, using the Ruger scope rings . The Ruger rings attach directly to the rifle without a scope mount . I mounted the scope as far to the rear as the ring mounts allow but I can't see properly without leaning my head far forward to reducw eye relief . Has anyone else had this problem and , if so, what is the remedy ? Thanks in advance for any help .
