new scope problems

[cheek9075]

any ideals would be helpful.
i just bought a new nikon monarch 8-32 and put it on my rifle. rifle is a rem 700 , i used leupold bases and ring.
my problem is with these ring , or any one piece ring, the scope will not zero at 100 yards, there isnt enough adjustment in the scope.
i have checked the ring with alignment tool, and everything looked ok, until i tried a two piece base and rings. then i find the back base is lower than the front base by about .026 inch.
i currently have the leupold bsaes and rings on the rifle, with a .026 inch shim under it, it seems to shot ok, 3/4 inch groups with factory ammo, i think the bases are not moving at this time.

ok now what, is it the ction on the 700 that is off, or what. thats what it looks like now. what's the fix with this rifle, is the shims ok or has anyone had any experince with shiming scope bases. have never had this problem before, so any ideals are welcome. thanks to all....

.
Remingtons are fine actions but the rear holes aren't quite right.
The weaver style bases are different heights
I use those with millet angle lock ring that take care of the windage problems.
I sure others have had this problem before.

Try a set of Burris Sig Zee rings W/the inserts. They will help cure the alignment troubles

Make sure you put the correct screws in. On some actions, if you put the shorter screws into the longer holes (no problem...yet) and the longer screws into the shorter holes, the longer screws will either drag on the bolt lugs and prevent complete seating of the base. I am not completely certain that this is the problem, but I had the problem once of putting the longer screws into the front base and wondered why the bolt was dragging. Switched the screws from the front to the back and Voila! Problem solved. If you find that you need shims, Sinclair carries them.

My first guess is that the bases are incorrect. If you put a new scope on a rifle and can not bore sight it at 50 yards, it is likely your bases, not the rings or scope that is the problem. Cranking that Nikon through half of its elevation range to get on paper at 100 yards sounds like your front base is too high. (are they perhaps switched around?)

Adding inserts in the Burris rings to "correct" this is like putting wheel weights on a rim of a car tire. It works and is expedient, but does not correct the root cause of the problem.

I would buy a new set of bases (even a cheap set of Weavers) and see if the problem sorts itself out.

You could shim the rear base?

i have tried 2 one piece bases on the rifle. same problem as before. everything pionts to the action being off.
i got the rifle for a steel, thought the guy just didnt know what he had when he sold it to me, i put a 3-9 nikon scope to hunt with , had not problems with the scope at that time, but the rifle would not shot. it was getting it to shoot 1 inch with factory ammo, and then i missed 2 turkeys and a deer in nov 09, shot it on paper, and sure enough it was of. thought i might have jared it but when i tired to adjust it it just would not hold, checked the scope, mounts and bases, put the alignment tool on the rings and everything was right, then i started looking , the front action screw was only in by about a thread and the action was moving in stock, i bedded it and fixed the screw problem. i then shot it agian and now we where talking, 1/2 inch groups with factory, it shoot good, i loaded some rounds and i was then on to something, so new scope, 8-32 nikon monarch. never tried one before i hope it is a good scope. but anyway.....
when i put the scope on the rifle, and went to bore sight it i could not get it to adjust down far enough, after looking at it agian if i take the rear screw out and tighten the 2 front screws(one piece leupold base) there is a gap between the rear screw and the base.
i order the burris rings and put them on rifle(2 piece base), put the alignment tool on the new rings and sure enough the rings did not lign up so the action is off. i put the inserts in the rings, +.10 in rear ring and -.0 in front ring and they now ling up. placed scope on rifle and was able to bore sight it. i hope this is the fix for my problem.

for a 1 piece base: Get yourself some jb weld and some shoe polish or whatever release agent you want. You may want to use some emory clothe to rough up the bottom of the base. Put some release on the reciever and base screws, put the jb on bottom of the base front and rear holes, lightly engage the outside screws into there hole and apply a light amount of pressure on the middle screws.

is this a normal problem, first time i have ever saw it. but then agian new to target shooting and guess i havent paid attention to it before. i was happy with 1 inch groups before.
someone told me when you get bit by the accuracy bug you where hooked for life. guess i'm hooked. if the new mounts dont fix the problem i will try the jb weld.

No your situation is not the norm, it sound like the action was drilled and taped at a slight angle. And thats what you found.
So what do you do about it? Good luck in getting Remington to do anything about it at this late a date. So in my opinion, custom made mounts, shims or the Burris Sig Z rings are your best options.
I would go with the Burris rings, quick, easy and cheap, there also the best on your scope, and there all I use, even on rifles that cost a lot more than a Remington.

I have seen a couple rems with this problem. At the factory they basically sand the profile of the rear reciever with a surface master and it is entirely possible for an untrained worker to go a little to far to take the machining marks off.I concour that bedding the leupold mount or shimming will work and dont forget to loctite the screws after you get ready to final mount the base.I sure hope you are using a leupold windage adjutable base,very important. Good luck and dont dispair.

cheek check the serial #. If it is an earlier model receiver (no prefix) then the rear of the action should be about .017" lower than current production models. I don't think anyone makes bases to allow for this anymore so shimming or bedding is the easiest fix.

 

[cheek9075]

ser starts with c86... is this one of them? the best i can tell it is .015 lower than the front. sounds bout right, i have the burris ring on it now. havent shot it yet, weather is killing us, like everywhere esle.

 

[dmg264]

No that is a later model, pre prefix won't have a letter in front of the #. I wouldn't worry about the difference though, it sounds like you have already got worked out.
