Over 14x for 100-200 yards? Don't you think that might be overkill and might severely limit field of view, produce a tiny exit pupil at high magnification, and impede the ability to focus at closer distances?
What kind of target shooting do you plan to do at the 100-200 yard distance? Will this scope need to be used in low light conditions? Help us understand what your use will be. Paper only? What size targets? What degree of precision? How accurate is your rifle?
I do have high magnification scopes. They are for special purposes. I would not recommend a scope over 14x for shooting 200 yards and in unless you are trying to shoot tiny groups at fixed, very small targets, like benchrest. And then, such scopes severely limit all other uses.
If it is target shooting only, and only at fixed range, and not to be used for other purposes, then yes, consider a benchrest type scope.
Weaver T-24 or T-36 are affordable fix power target scopes with decent reputations.
A 6-24x variable with 50mm objective might be another option. I have a no longer produced Burris Black Diamond 6-24x50 that is superb for such use and for load development of my handloads. These are big, heavy, long, somewhat unwieldy scopes. But the better ones are very good for their intended purpose. I have mine QD mounted in a LaRue 1.93 SPR mount, because the scope, with sunshade attached extends so far forward, that it would hit my front folded sight if mounted at standard 1.5" height, and because I want to be able to easily remove it and use other more modest optics for general purpose use, and be able to put it back on and have it return to zero.
A true benchrest competition scope is exemplified by the Leupold Competition Series - all fixed power in 35, 40 or 45x, very precise, at about $1,100 each, street value. They don't have to perform in low light or at long range, but have extremely precise adjustments and decent glass for those distances. National benchrest shooters often choose one of these. They are not intended for field use and are not ruggedized. Is this what you are looking for or do you need more versatility?
