K22: My choices for my favs are close to Kirk J's - first would be the Weaver V-16 (four to 16 power variable with A/O feature) with the fine crosshair and fine dot reticle.
Next would be the WONDERFUL - no the OUTSTANDING - Leupold 6.5x20 A/O with E.F.R. feature. Mine have the fine Du-Plex reticles but if I could find one with the Leupold Dot or fine crosshairs and fine dot reticle I would buy it instantly! My reasoning for putting the Weaver V-16 as "first choice" over the Leupold 6.5x20 E.F.R. is the vast difference in costs.
Good luck with whichever you choose if you are looking to scope up some more rimfires.
