30-30 reloading recommendations

[dakotah]

With the H335 and 170 grain flat points I shoot .75 inch groups with the Marlin with a scope on it. That group doubles when I take off the scope and use a aperature rear sight and a post front (Lyman 17a) -- If I could use an aperature front sight the groups would go down. My eyesight is such that the front sight is too often fuzzy w.o. glasses. If I were corrective lenses so I can focus on the front sight the target gets blurry -- but this is the best for me. With aperatures sights the fuzziness is not such a problem. But the lever action silhouette groups I shoot with wants us to use post front sights.

The Winchester 94 also has a Lyman 66 rear sight (vintage) but it has an original front sight (Sort of a round ball on a post) I can only shoot 1 - 2 1/2 inches. The groups vary, but I blame my eye sight rather than the gun or load.
