A Leupold 2.5x20 will be perfect, great eye relief & eye box with enough power for the 300Sav. and plenty of FOV to make it the fast handling rifle the Sav. was meant to be.

This is a Weaver K-3 on a 99, the Leupold is a little more compact and just looks better and works better. A Weaver V-3 is a nice compact scope that would work well as is the Leupold VX-II 1x4x20
