If you go to the Bushnell website they have the elevation range and eye relief listed for their various scopes. I am very fond of the Bushnell 4200 series, they have proven to be very durable, read that as I have never had a problem with one, with a little careful shopping they can be had at very good prices. I really like the rainguard feature, the adjustments are always spot-on (I use mine for competition mostly and am constantly running the adjustment knobs), and optically they do not take a back seat to anyones product in or near their price range.
I have found that most people who bad-mouth them are basing their experience on a $29.95 blister-packed product that they bought at the local box-store and can't understand why it isn't any better than it is. When Bushnell dropped the Bausch & Lomb product name and renamed it as 3200 and 4200 Elites, to my mind, they would have been wise to market them as Elites and drop the Bushnell name from the product, that way many of the folks who automatically badmouth anything with Bushnell in the name would have been less likely to badmouth it just because it has Bushnell in the name.
I recently purchased a 4200 6-24 side focus and could not be happier with a scope, my next purchase will be one of their 6500 series scopes which have an elevation range of 80 inches.
While the 4200 series does have some limits to the elevation adjustment unless you are going to try to "click" up all the way from 100 to 1000 yds the most simple way to handle this is to use the Burris Signature rings with the off-set inserts and you can gain over 20 inches of elevation simply by switching inserts.
With all of that being said if you watch the ads quite ofter you will find Leupold 6-18 for around $350 to $375 and 6.5-20's for around $500 these may get you to 1000 if you plan on "clicking" up but be aware that if you chose to "click" up you will be at the top end of your adjustment and the scope will more than likely have sluggish response to to click-ups or may wander in horizontal as you move up and down. It is much better to optically center the scope as near as possible to the range you will be shooting.
Sorry for the long dissertation but I could not think of a way to respond that would be any less wordy.
