I acquired a Burris Signature Select 8-32x for $100.Yippee

But, it only has 22 MOA of total adjustment...and it will be used for long range shooting.
I was going to put 10 MOA of up in some Burris rings, and then hopefully have the scope 1 MOA from bottoming out of adjustment, hopefully giving me around 20 MOA of up adjustment, getting me to around 1000 yards with my 6mm Ackley.

Will have the scope this close to the bottom of the adjustment range hurt anything?  I guess I could just leave it sighted in around 500 and dial it down to 100, 200, etc. when needed.

First off chances of it actually being perfectly centered after you mount and zero it is very slim.  It is very possible if you put a 10 MOA base on it you will not be able to get a 100 yard zero or even a 200 yard.  Also by bottoming your adjustment it will limit your windage dramatically because you will be at the edge of a round tube.  But windage adjustment is not as important at close shots, but you may be stuck with a 300 yards zero and actually need windage adjustments, hard to say.
It is amazing to me that they actually make a scope with only 22 MOA, what a waste.  If I were you I would turn around and sell it for $300 and buy an actual target/tactical scope if you truly want to shoot long range.  Like a super sniper

Get a 20 moa base, that will certainly help. but getting at shorter yardages will suffer some, what type of reticle is in it? I too think that the scope is seriously lacking in verticle, and that another scope might serve your purpose better. You could always just shoot at shorter ranges.

I am with supertool on this one when it is that close to the outside of the tube it is putting pressure on it not allowing for your needed amount of windage adjustment. Maybe this will help explain what supertool is talking about sorry about how sloppy it is 5 minutes in paint.

aside from the adjustment issue...... I would think $100 for 8X32 Sig. Select is a pretty damn good deal!

So it won't harm the scope in any way?  I want the most windage as I go up in adjustment, so starting out in the bottom will help that too.  Out to 300 or so yards I shouldn't need more than 2 MOA of windage either way, then I start cranking the elevation up which gives me more windage also.

To the best of my knowledge I don't think it will hurt anything.

If my thinkings are correct the more you you adjust your scope to shoot farther the less windage you will have so at 300yds you will have more left and right MOA adjustment than you will at a 1000 because it will be even more bottomed out than it is now.

Chris is right.  Say you are able to get a 100 yard zero with a 10MOA base, but the reticle is at the very bottom of the circle which is fine as you won't need much windage for 100 yards.  Now lets say you are shooting a 107 grain SMK at 2900 FPS.  At 700 yards you are going to need about 16 MOA to make that distance.  Now since your scope only has 22 MOA max (probably a little less) of travel the other way you are going to be approaching the top of the circle and now your windage will be once again hampered because you will be hitting the sides of a round tube.  Now at these distances you will need the windage to make those kind of shots.  800 to 850 yards will be the very max you could possibly shoot with that scope rifle combo which will put you at the very top of the round tube and you will hardly have any windage at all to play with and this distance is where you may need a lot.  If you have a 10 mph cross wind and are shooting at 700 yards it is going to blow the bullets about 35 inches to the side.  So that is about 5 MOA which you may not be able to dial in because you are in the round side of the tube again.

Really one of the purposes of a tapered base is so that when you reach the longer distances it puts you in the center of your scope.  With scopes that have 70 to 100 MOA of adjustment when you put a 20 MOA base on them that works pretty good to keep you centered at distances from 700 to 1000 yards where lots of windage adjustment may be needed.  But with your scope it just does not have enough to make it work like that. 

Now if you are planning on staying less than 500 yards, I don't think you will have a problem at all unless you find a 30 or 40 MPH cross wind or something, LOL.  500 yards is plenty far to have a lot of fun at too and really stretch your skills.  Also you could use the mildot reticle so hold over for distance and left right for windage.  It won't be as accurate as dialing it in, but you could do it.

Yep...I thought about this, and I'm going to need a different scope.  It should work good out to 600-700 fine though.  I was planning on a Berger 95 grain around 3300 fps, or 105 Amax 3100ish. 

Anyone wanna trade me an Nightforce NXS for my Burris?  US Optics may be accepted also...Yippee
