Why is not recommended to use turn in style rotary/dove type rings with rear windage adjustment aside from the fact you shouldn't use your scope as a pry bar to turn in the rings? The reason I am asking is that I need the extra windage adjustment because remington buffed too much off the rear of the receiver and therefore the front and rear bases are not aligned. The windage adjustment is not at the optical center and is almost all the way in. There is a half a shim on the rear base which rotated it level with the front base. This gave me a little extra adjustment. I am using Kelby rings and Davidson bases. I had to resight the rifle in this year which I shouldn't have to do and I am thinking that maybe the shim and the fact the scope is not at its optical center has something to do with it or maybe its a scope problem. I have a nightforce 8-32X benchrest scope. All the screws were tight on the rings and bases.
Any opinions or suggestions? Thanks

Since most scopes tubes are constructed of aluminum its not normally a good idea to use the scope as a lever to twist in the front ring because the possibility exists that you might tweak the tube.

Just use a bar of the appropriate diameter to twist in the front ring and don’t worry about it.

For starters, check your bedding. Make sure there is no uneven pressure against the barrel. Actually, get yourself one of the handy, dandy Leupold magnetic bore sighters and mark the cross hair's position on a piece of paper. Leave the magnet attached to the muzzle and remove the barreled action from the stock and have another look. That will tell you things you may not wan't to know...

Hey Hogman, If you use a HEAVY Scope on a rifle which has a relatively "robust" recoil, the Scope will try it's best to remain where it was prior to the shot(Physics). And what can happen is the Scope will "slip" forward inside the Front Ring and the Rear Ring will "rip" through the two Windage Adjustment Screws.

Basically the only thing holding the Scope to the rifle is the Front Ring. If you tighten it enough to get a tenacious grip on the scope tube, then it is generally tight enough to "mar" the tube. You can put Rosin, Glue, Sand, Tape, etc., inside the Ring, but you are fighting a problem that does not need to exist.

And you can add a small Tap Head Screw to the Rear Base directly in front of the Rear Ring so the Screw head keeps the Ring from moving forward. This requires some precision measuring, drilling and tapping to execut eit properly. But as you look at those two Windage Screws, you will realize how weak they are.

Go to the Burris web site and check out the Burris Signature Rings and Bases. They have Synthetic Inserts designed into the Ring which allows you to get an excellent grip on the scope with no chance of maring it.

And since you have a bit of an "Alignment Issue", they also make Eccentric Inserts to replace the standard Inserts. You can turn these in the Ring to compensate for any Alignment Issue you are going to experience. It will be clear once you look at the Burris Site. Just get the 3-Eccentric Insert Set.

An additional benefit for those of us who choose to take some long distance shots, is you can use the Eccentric Inserts to create the effect of having a "Tapered or Beveled Base" to lift the rear of the scope.

They make the Burris Signatures in the Redfield Style(which you really don't want), Dual Dovetail and Weaver Style.

Once you try a set of the Burris Signatures, I doubt you will be happy with any other Rings - including those REAL EXPENSIVE Rings.

Well said.....These are good stuff IMO.
