Scope ring problems

[Muleys 24/7]

I have a 300 Weatherby with a VX3 Leupold scope. I originally had a set of Leupold rings on it but I had to shim the back and in order to get the crosshairs on paper, I didn't like the whole shim idea because I believed it was affecting the accuracy, plus after banging off about 40 rounds the shim would start to slide out. So I recently purchased a set of one piece ring and Base tally scope rings. After installing the talley rings I took it to the range to find out, my elevation adjustment on scope was maxed out, and I was still shooting 3 1/2 feet high.

I'm looking for some help on a way to resolve this problem .
Should I take Dremal tool and Sand down the rear base? Or send my scope into leupold to get it adjusted somehow?

This is a major problem. Sound odd that you'd have this issue with two different mounting systems. I bought a rifle once where there was a burr from the tapping process on the receiver that caused issues. Check that, check ring height uniformity, if that stuff is ok, it's a problem with the receiver itself.

Is your scope tube sitting parallel with the barrel and bolt? I would measure from the top of the bolt to the base and to the scope tube and see if it is the same at the front and back. Im not sure how much difference you can have before it causes a problem but checking that would be a good place to start. If the base is made for the gun it should be made to fit and align the scope correctly. Is this a new gun or new to you? Have you ever had any other scope or mounts on it? If it is pretty parallel to the bolt you might try another scope if you have one to see if it does the same thing.

Yeah it's extremely frustrating especially after just buying a set of $50 rings and it didn't fix the issue. There is no burs on the receiver. I'll try to check the ring height

MM, these are the right rings for the right gun according to the package. I've had this gun ever since it was brand-new but with the original Leupold rings I always had to use a shim that the gunsmith put in there. I like the idea of mounting a different scope to see if I can boresight it with the new rings. If it will not boresight with another scope maybe I should take the rings and to get them custom fitted to my receiver?

Another question would be where you purchased the scope? I received an email from leupold a few years back that there was a bunch of counterfeit scopes coming in through ebay with the ways to tell the difference. I've always had good experiences with them myself, but have always bought from a dealer.

I bought the scope from a reputable dealer, and registered it for warranty through Leupold .

Is your base 1 piece or 2 piece? If its 1 piece try setting it on the gun without the screws and see if it sits square on the receiver. How thick is the shim the gun smith made for it?

The way I read your post Muleys is you don't want to lower the rear of the scope. Your line of sight is already to high even with the elevation adjusted to the scopes max. You may be able to shim and bed your one piece base enough to correct the issue.

The scope ring and base are one piece. But there is 2 one the front and rear.

Packer,Wouldn't I want to adjust the elevation up 3 1/2 more feet from the original aiming point that is already maxed out in elevation? In order to get that elevation I would have to drop the rear of the scope correct?

Yes everything sits square on the receiver the old shim was really thin I'm not exactly sure what size it was.

I would get a 1 piece Leupold base and see how it sits on your gun. With a 1 piece I think shimming it would be alot more successful if you do have to shim it because the 1 piece will be alot solider and the other end thats not shimmed will help keep it solid too.

I agree with the one piece base idea. Also if a shim is required, shim it under the base where you have the screws through it and bed the base to ensure even contact with the receiver both front and back.

You are correct, I was thinking a little backwards, by lowering the rear of the scope you are effectively raising your crosshairs and line of sight. My bad, should have thought about it a little more before inserting my foot !!!!!

I agree about the one piece being more solid, but it will be a lot harder to get a round in and out. If possible I would like to get these talley rings to work, but it may require a little custom machining, plus i'm over trying to buy more scope rings and bases. Thanks

The way I am understanding it you are shooting 3 1/2'' high with the scope down as far as it will adjust. Assuming the problem is not with the scope you would either have to bring the rear up or the front down to get your scope where you can sight it in.

Hard to tell in a pic but the rear looks lower then the front in relation to the bolt to me.
