Re: Rimfire Scope......Advise?
Some thoughts.
First, I agree with jbell, isaccarlson, and Hunter 24, I consider quality glass as important for rimfire as centerfire. I am not less concerned with seeing and hitting the target so I am not less demanding of the glass.
All that being said, if you are only invested in a MKII perhaps $250 or $300 is not too cheap. My MKII did not do better than 3" at 100yds no matter what I fed it so my opinion of them is rather negative. To put it mildly, I think the extra hundred or two spent to get a CZ is a marvelous investment. Certainly at $300 you can get glass that is not going to fall apart on you immediately.
So, here are some thoughts on .22lr glass for target shooting and competitions...
1) Light weight is important, many .22lr competitions have low weight limits such as 7.5lbs. Heavy scopes can push many guns over.
2) Adjustable parallax that will focus close enough to be usable at least at 25 yards and preferably at 50ft. The adjustable parallax is vital both for making it possible to see both the image and target clear at the distance you are shooting and also for minimalizing parallax error if your head is a little off center behind the optic. Many .22lr competitions are held at close range whether you or I like it or not and close focus is a must.
3) A fine reticle is important for all target shooting as it simply allows for a more precise aiming point.
4) A high top end magnification is preferred by most every competition shooter. This is not just because it provides a more precise aiming point, though it does. Frankly, holding .5moa with a simple 9x is probably not a challenge for anybody. I, and I expect many other shooters opt for higher powers so we can see the holes at the distance we are shooting. It is just much easier to practice and compete without constantly having to look at a spotting scope.
5) A scale reticle for wind holds will be found useful. Most folks dial for drop and hold for wind, you need a reticle with markings to do this well. A mil or MOA hash reticle is best though I use a mil-dot. Even if you know distance and don't need a scale reticle for ranging if you are shooting long distances outside in the wind with a .22lr you may find the scale vital for wind hold.
6) Finger click adjustments are pretty much standard now but I figured I would mention them because I have recently had a scope that did not have them on a .22lr target rifle and it drove me up the wall always having to dig out a tool. As everyone has said, adjustments matching the reticle are best, my .22lr scope has mismatched adjustments and some day I will find a scope that satisfies my other requirements as well as the one I am using and sell it.
7) If you want to go to 200 I expect that you will need a lot of internal adjustment. I'm not going to do your homework for you and look up exactly how much but you need to make sure that you have enough travel with the scopes internal adjustment and base to make the drop at 200.
Sooo, I'm using a Zeiss Conquest 4.5-14x mildot at the moment. If its reticle and adjustments matched and it focused just a bit closer, to 50ft I would never leave it. As is, it does most of what I need it to.
