It's been 15 years since I scoped a springer, back then Leupold 6.5-20 EFR was the way to go. Now that scope sits on my Rimfire silhouette rifle, a CZ 452 Grand Finalle. I need a scope and mount for a .22cal HW-85. Prefer a variable with at least 20X top magnification, and a lot of elevation range, that will withstand the dual recoil of a springer. Budget is around $500, was looking at Sightron S-tac 4-20 what others would be worthy contenders that I should consider?
