If you poke around in the US sites, Leupold and Nikon are about equal in sales-something like 40%ea. Still although Leupold has good glass and excellent service in Canada (which seems to be the big deal with them) it is doubtful their glass will ever be as good never mind better than Nikon. Dont get me wrong-I own both and have a newer VXIII on my Ruger 30-06. Still putting a 12 or 14x on a rimfire that has an effective range of 100 yards is a little silly and can cost more than the rifle. Aside from that the VX series is not designed for rimfire. Basically if you cant see it with a 4x you likely cant either hit it or kill it. Mind you I have only been using 22s since 1965 so what do I know eh? There is no logic in putting an expensive centrefire scope on a rimfire. Aside from the focal length thing. My $0.02 .
Man... you need to explore the world of rimfire. Take a read on Rimfire Central and look at some of the gun and scopes. Rimfire rifles are not only used in dusty gopher pastures and not all are toppped with cheap 4x scopes. Target shooters can have 40x scopes that costs thousands.
You say the VX series is not for rimfires?? Leupold has the VX II 3-9x33 EFR Rimfire, designed especially for rimfire shooters, take a look on there website.
You also think a .22 is only effective to 100 yards?? Maybe try 300 or 400 yards.
