Random thoughts to consider...

Well... if 9x isn't enough for 200yds that sounds like you want to do more than just hold center on the target, like be able to see holes in the target? If so, 20x scope. Otherwise, just cranking up the magnification isn't going to yield much in the way of greater accuracy with a standard AR platform and factory ammo if that's what you're using?

200yds is within the distance where higher quality glass isn't required for sunny day shooting. And it's not a distance where you're going to exercise the adjustment mechanism much going between shorter distances and 200 yards. So really, you won't need much of a scope unless you just want to spend $600 on better glass. That said, better glass can make a shooting session more enjoyable cuz it just looks better. I'd put a higher emphasis on a thinner target reticle for target shooting, target turrets are nice to play with and side focus.

ps. Don't overlook fixed magnification scopes. 99% of the time guys just leave their variable magnification scope on the highest setting anyway if all they're doing is paper punching.
