I use Leupold's on my Ruger No.1's and find them ideal. Any of the better scopes (Leupold, Nikon, Bushnell Elite, Zeiss, etc...) should have enough eye relief IF the No.1 stock fits you correctly. If the stock doesn't fit correctly (scope appearing to be too far away but no risk of getting scope cut), there are offset rings made for the No.1 by several manufacturers.
As I said before though, I've never had an issue with Leupold's or Swarovskis'.
