I've got one of the Leupold 3X9 EFR scopes on my Sako Finnfire. Great scope!
It's nice to be able to adjust parallax down to 15 yards for close up shots on 9X.

But, my all time favorite for a rimfire is a Leupold 3.5X10 A.O.
You can adjust the parallax down to about 25 yards for shooting up close on 10X.

Have one of these on my Cooper 17 HMR. It gets used a lot for "yard varmints"
Gotta guard my bird feeders from these pesky critters!
