Sounds as if you might have been better off to use the non-Zee Signature rings. Then you have lots of windage built into the rear scope base, and can use the eccentric inserts for elevation.
Hmmm, I went with the 30MM Zee rings because they looked more sturdy, and I think those were the only ones that fit a picatinny rail.
Having said that adjustable windage in the rear ring could be a very nice feature...
Just yesterday I installed Burris Z rings on my 40X with a Weaver T36.
With the zero inserts I was 10" high and 2.5-3" left mat 50 yards. The 20's would appear to be the corrent starting point as I needed 20 moa.
With the inserts in 20's in the front rings, I was 20" high and 6 inches left.
I switched the inserts to the rear rings, and that put me close enough that the scope could now be adjusted for 50 yards.
I read the instructions to indicate the 20= and the 20- were to be used together rather than one in the front ring and the other in the rear ring versus one being in the front and the other in the rear.
This was a first time experience with Z rings and inserts.
Hmmm, you know I suppose I could just get a package of inserts from them.. and get the +20/-20 combo.
Yea, you are supposed to use a + and a - in the same ring. So a +20 in the bottom half of the ring, and then a -20 in the top half of the ring. You can also use them to correct the side to side positioning of the scope if your scope holes aren't centered buy putting the inserts sideways in the ring, +20 on the right of a ring, and -20 on the left for example.

I suppose my main question is if there is something wrong with my scope/mount/rifle, because I have to add, according to burris, "20 MOA", to zero my rifle at 100 yards. According to my calculations i'm only adding 10ish MOA.
Without those inserts, I'd be almost out of elevation in my scope...
