I'm looking at several scopes that have ~40-50 MOA adjustment available and I want to shoot out to 800-1000yrds/meters with a .308.

Assuming that the scope is centerd in that 50MOA that would leave 25MOA up adj. and 25MOA down adj. correct?

So if I add a 20MOA base I'd have to bring the scope down ~20MOA to 0 at 100yrds right? That would leave me with only 5MOA down adjustment... (even less if I get a scope with less than 50MOA).

I read that most scopes adjustment at the extreme ranges of their adjustment are not as accurate... ie 1/4MOA at the lower/upper limit isn't exactly 1/4MOA at the center. Is this correct?

So, if I use the scope for hunting at 100-200yrds and shooting at pictures of Osama at 1000 will the adj. be ok at the hunting ranges of 100-200 or will they be "screwy".

Would it be worth swapping scopes for hunting/target on the same rifle?

Trying to understand all this stuff....

Try this buy the right scope - MUST HAVE A  30mm tube.  A .308 rifle sighted to ZERO at 600 yds will drop 230 inches at 1000 yds or 23MOA.  Note Leupold scopes made to shoot LONG RANGE are disignated LONG RANGE for example the 4.5-14 Mark 4 and VX-III have 100MOA windage and elevation adjustment if you buy the 30mm tube Long Range version. With standard rings and bases most scopes should get you out 600 + yds but there is a huge difference after that. The 10x42 Super Sniper is a very popular scope at a reasonable price with 30mm tube for more internal adjustment.

 

Once you have a scope that will work get some Badger rings and the plus 20 MOA or plus 30 MOA base.
