Re: 1000 yd scopes
I agree with most of the above and would add that there are a lot of other good values. You can find lots of discussion in the Optics Section of these forums.
It will likey come down to budget and you should get the best scope you can afford. You should also use a 20 MOA rail such as those made by EGW and others. As such, you'll have plenty of elevation adjustment for any of the scopes including the Zeis mentioned above and you'll still be near the center of your adjustment range at 1k.
