I was wondering if you might take the time to elaborate on some scopes increasing their MOA increaments as they move through their range. Ie, your reply here;
Your post has me wondering if I need to upgrade to another scope. Anyway, if you can take the time to reply either here or on the site, I'd appreciate it. You said a students scope was doing this. I'm sure myself and others would appreciate more info on this.

Sure. The truth of the matter is that most scopes do not track in even increments throughout their travel adjustments. Most start out moving what they are supposed to but when that erector spring starts getting compressed or loosened, some strange things can happen and the value of each click might change.
So, everytime I work with a new gun with/or a new scope, I put it on a grid and check it's travel. In my unique position, I get to see many different scopes and their capabilities. THere are two things I am looking for: click value uniformity and repeatability back to zero. Some scopes might have one and not the other and some have problems with both, and some have no problems at all.
For the most part, Leupold and Nightforce seem to be the best in my experience with both scenarios. I have seen a few Leupolds that went 1/4" through two revolutions and then suddenly increased slightly but they always returned to zero and were repeatable so that a drop chart could be altered to fit the change. I have not tested near as many Nightforce for these scenarios (probably 20 to 1 for Leupys)but I must say I haven't seen one yet that changed value.
Then there is everything else. All can work and all can have lemons. I will say that again: All scopes CAN work and ALL can have lemons. There is no point in debating scopes here, but the others just have a track record of having more problems from what I have seen and that is just my view from my standpoint (so please don't get all hot and bothered over this and start a flame session [img]/ubbthreads/images/graemlins/wink.gif[/img]) So that doesn't mean you can't buy a Weaver, or a Burris, or a Nikon and not dial it up. It simply means just checking it and correcting your drop chart if you notice a value shift.
I think all of those companies have good models and debating anything about a scope other than dialing capabilities is like debating what is the best color or the prettiest supermodel. [img]/ubbthreads/images/graemlins/wink.gif[/img]
