Have a Savage 64f semi auto 22lr. Want to mount a regular scope not a rimfire scope. Bought some rings that are for a 3/8" dovetail receiver mount. The scope is a Tasco target varmint 2.5x10 x 42mm. Do not have a any specialied tools just for mounting a scope. Have some basic questions on where to begin. How far apart and where should the mounts be positioned on the receiver? Also, how to adjust the scope for level and eye relief? Any tutorials on this forum or on the web? Thanks for any help.
