Try a low power variable in the 1.5-4 or 1.5-6 range. For this rifle you don' t need a scope with an objective larger than 32mm.

There is nothing wrong with the 30-30. It is not the flattest shooting cartridge in the world but out to 200 yards it is very deadly. At my local range I have seen some gentleman make some shots at distances that I would not have believed without actually being there.

If I were to use the rifle I would shoot Winchester 170gr. Power Points.
