I'll be the 4th in line to recommend a fixed 4x scope for rimfire

Practical power
As with so many things relating to firearms people are quick to shout "more power" but as is so often the case less is usually more. I've personally gone through the "max-power & max-variable" phases in my life, not just with rimfire but other firearm optics as well. But it wasn't until I started using fixed, lower power scopes that I truly became a better shooter
and started to have more fun. I learned to range better, I learned to comp better, and as a result I became
much faster in the field.
I've found that for the most part those sporting scopes with the widest & highest variable range are some of the absolute worst shooters, usually having next to zero instinctive abilities and equally as bad ranging ability. Of course the latter means they tend to rock a fancy rangefinder that they just have to tell you how much they paid for it.
I learned my lessons and today I only run fixed power scopes on my working guns, most are 4x or less, the highest is 6x. Even my "go-fast" crap sport 1.5/2/3/5 power ACOGs, nothing higher. I do have variable stuff along with some high power optics but most are vintage collector scopes I've acquired over the years, many are mounted to vintage rifles they were originally mounted on during the early to middle part of the 20th century.
When asked, I suggest people start with a fixed power, usually a 2.5 or 4x, then learn to master it FIRST. If you
truly do master it and then find you still need more, then and only then step up some. Trust me when I say that in the long run you'll become a better shooter, I know because I went through it myself

I think I should mention that I'm referring to scopes on working guns. I'm not a paper-puncher kind of guy, nothing wrong with it, just not my thing. So my perspective comes form hunting, moving, working, field, etc. If you are asking about straight target shooting, I think one of the bench type fellas would give you more better good advice in that realm
