blairvt,
Read this. It's from the Leupold service department.
Dee,
The Browning 78 is similar to the 1885 High Wall rifle. In fact, it will use the same bases. Our two-piece STD base is number 50012. To make this base system work on the 78, you will have to use two different heights of rings. For example, a low ring in the rear and a medium in the front.

Good Afternoon, I have a Browning B-78 octagon barrel single shot rifle which uses a two piece scope base set. Do you sell these bases? Thanks for your help! Dee
