Optical Centering of Scopes

bpost
I counted the 232 clicks of adjustment on my Burris 8X32 and have set the scope to center on both windage and elevation and windage.

I also ordered an adjustment set of inserts for the Burris Signature rings.
Question;
Is it better to make the adjustments on the fron or the rear rings to bring the scope into center?

    I wouldn't see any factors that would make a difference[?]

    Hello I don't want to seem to be jumping in the middle of this discussion but this idea sounds great . I have 2 questions #1 if you put eccentric spacers around a scope how do the rings fit around something that then would be over one inch in diameter. # 2 I use 2 pieces of one inch steel rod turned to a point one in the front ring and one in the rear ring faceing each other to check alignment of the rings to keep from twisting the tube of the scope .how do you avoid this with accentric inserts. Thanks in advance .Karl

    The best bet is to split the difference if that is possible. How far off is the adjustment now? if it is only a hare off, or even 10MOA (58MOA total adjustment 232 clicks divided by 1/4moa clicks) then that should still ensure a tight adjustment with respect to the springs. Unless you reach near max adjustment in any direction, the scope should hold zero well.

    why chase the game when the bullet can get em from here?....

    The rings referred to are oversized and concave on the inside surface. The inserts are sized to fit the scope tube on the inside and convex on the outside. This works like a pillowblock bearing holder allowing the scope to remain straight even though the bases are out of line.

    Hi Karl,
    The Signature rings have the capability of eccentric movement supplied by the polymer inserts inside the rings. They are available in ZERO +/-005, +/-010, +/-020, the use of the combinations make more that a few clicks unnecessary to bring the scope into zero. Experienced users can adjust scopes into the 10 ring in just a few tries. The system also removes the bending forces applied by misaligned rings.

    There are several combinations available that can essentially zero the scope while holding optical zero. Just C explained a lot to fill in my missing pieces. Now I have to apply practical knowledge to actual experience. That can at times present the real problem!

    Thanks for the reply .These rings sound like a better mouse trap. I will buy some to try. Buy the way bpost 1958 if you go to the CMP web site and look up the winning CIV. HARDBALL team match at Camp Perry this year you will see a picture of yours truely. Even a blind hog can find an acorn now and then cheers Karl.

    Sorry, but counting clicks is generally not a definitive way to center the reticle. Often you will find several 'dead' clicks, even dead revolutions, at one end or the other of travel. Not to mention some strange optical aberrations from time to time. Best bet is to look through the scope as you carefully rotate the scope in a pair of ' V ' grooves. Making adjustments as necessary until the reticle remains constant relative to whatever 'aiming mark' you are using. A firm cardboard box with a ' V ' cut in the top edge of two opposing sides works for this - be careful as you rotate the scope - not to move or crush the box.
    Best............!

    Hey thanks for that . I'll give it a try to see how close it really is.
