Their explanation is better than I can do.... ;D

Quote
Choice 1, Adjust the Front Ring
You simply put the - insert direclty toward the point
of impact and + insert directly away from the point of impact. Fire
another group. If your group is within 3" of your desired point of impact,
use your scope's internal adjustments for final sighting.

Choice 2, Adjust The Rear Ring
You simply put the + insert direclty toward the point of impact and - insert direclty
away from point of impact.

Josh84.
You do not say at what distance you are still 6" high. The excentric bushings come in 5, 10, and 20 Thou offsets. The way I would do it is to first get the x-hair in the optical center. Next I fire a shot at a long target 100yrds and see  how low or how high the rifle shoots.

You say you used up all the scope adjustment. I guess that would be 1/2 of 60" or so, or 30 min or 120 1/4" clicks. plus the the 6" you are still shy for a total of 36".

OK 100 yards= 3600 inches.and say your rings are 4-1/4" from center to center.
We now divide 3600/4.25=800. Next we divide 36" by 800 = 0.045" that is the the amount of you have to raise the front ring.

So since you only have 0.020" Burris excentrics you raise the front by 20 and lower the rear by 20 and your are within 4" of  center..(0.005x800=4")

This calculation can be used at any known distance say 25 yards, but your minutes have to be divided by 4. That is 4clicks at 100= 1", 4clicks at 25yard = 1/4"

Now you know what you need to do after you do your calculation. Math is a wonderful science. Any sight can be adjusted in this manner. You get the best out of your scope when your x-hair is close to the optical center.

Use the mirror method to optically center the reticle.... ;)

Centering of a scope's adjustment dials
The elevation and windage adjustments of a scope are easily centered. Place a small mirror against the objective end of the scope. That would be the end farthest from your eye as you look through the scope. Make certain that the mirror is large enough to cover the entire objective. It must also be flat against the objective. With the scope's power selector ring set at the lowest magnification, look through the eyepiece as you would while aiming at a target. If the scope's windage and elevation adjustments are off center, you will see two images of the reticle (cross-hair). To reach the center of the adjustment range, simply turn the elevation and windage dials until you see only one image of the reticle.

Sorry, it's not my trick Larry, it's from Leupold, but it's always good to share with my friends. ;)

The burris offset rings work great, how much correction you get depends on the spacing between your rings, you can use two pair, one in front and one in back, opposite directions will get lots of correction.  Larry

Yup, .22Lr rimfire shooters use them to shoot at 200yds, works very well. ;)

yeah i am 6 inches off at 25 yards with my old scope, and just installed a 6x18x50 banner on it, but can already tell by looking through the bore and trying to set the scope that i am still at least 2 in high at 15 yards.  so a little closer to on, but still off.  am currently using regular burris zee's, because they were an accidental purchase (thought they were sigs) but will be buying sigs for this rifle (my 204) and for my 500 when it gets back.  thanks a lot guys
