I currently only have one .22 rifle (Marlin 880SQ) that I use for everything from target shooting to squirrel and coon hunting. So, the perfect scope is something i've been looking for as well and I just ordered a Nitrex TR2 3-15X42 with the EBX Ballistic reticle that I believe is going to be able to cover all of my needs.
My idea of the perfect rimfire scope is one that has (this is going to resemble the scope I just ordered, but for good reason):
1. A wide magnification range for both hunting and target shooting (2.5-16 like bushnell).
2. Side focus that that goes down to at least 25 yards (10-15 would be even better).
3. An objective lense that is big enough for target shooting and low light shooting but not too big to be easily carried in the woods (40-42 is my favorite).
4. A ballistic reticle that allows for quick shots at a wide variety of ranges, but one that isnt too cluttered for hunting. Also, not too thin for hunting but not too thick for target shooting.
5. Ballistic software to go with this reticle so that I can match it to my exact ammo.
6. An illuminated reticle option.
7. Open/pop-up turrets (1/4moa) that are very reliable for the situations where there is time to make adjustments for longer shots.
8. All the obvious stuff like crystal clear lenses, as light as possible, durrable, and of course affordable. I would be willing to pay anywhere from $250-$400 depending on the quality. I know a lot of people dont like spending that much on a scope for their rimfire, but some will spend well over double that. I think that most of the opticly-informed people on here know that a relatively decent quality scope is going to start at around the $250 mark if not more. There are scopes that cost less than that like the Muller APV that have had many great reviews, but that's not a feature rich scope like the above mentioned. Again though, this is all just my opinion. Hope maybe some of it was helpful.
I was going to buy a 4-16X42 Monarch with either a mildot or BDC reticle, but I wanted something that could focus down to less than 50 yards. It was the top runner until I saw the Nitrex and the deal they had on them. Wasnt going to buy a scope until next summer, but I had to jump on the deal.
Anyways, that is MY idea of the perfect rimfire scope. I know a scope like that isn't going to be as light as a 2-7X32 or have as much magnification as an 8-32X50, but it's right in the middle of both of them and I think that kind of scope covers a little bit of everything. The only way to cover absolutely everything is to make an entire line of scopes to do so:)
