Just happened on this thread and I think Leupold has told you what you need to do to correct your problem, as it looks like that scope is not level in the picture you posted. I see MM mentioned the same thing and I have to concur that the rear of the scope looks lower than the front end in that picture.

Keep us updated on this.. oddly enough I am having the same problem. I took mine into a gun smith and had him start from scratch but haven't shot a second time around. Curious how yours/mine unfolds.

Years ago I was having a problem with a vintage custom mauser action .300Wby that a friend of my Dads gave me. I had bought a new 4x14 VXlll for it and was having trouble mounting it. Called Leupold and one of their techs suggested that the mounts on ir were really not correct and I probably should change then. They sent me some new ones and guess what.....problem solved. They know their business and really help out. Their optics are pretty fair too....LOL

Last night I mounted the new bases that Leupold told me to buy and got everything put back together. This morning I hooked up my bore sight and it doesn't look good. Still can't get it to zero on the boresight, it seems to appear about the same as the tally rings and bases. I think I'm going to have to take it into the gunsmith and get something custom done. I've now been through three different sets of rings and bases At this point I'm getting frustrated. I'm hoping to have the gunsmith modify my tally bases so I can return all these other ones.

Hey Montana, what rifle do you have? Do you know exactly what you're gunsmith did, I'm curious to see your results.

I have a Browning Abolt 300 WSM. I didn't have anything special done. I just wanted eliminate as many variables as possible, which unfortunately included my inexperience:)

When you say it won't zero, is it windage or elevation? From you other posts I assume its elevation.

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?
Another question...what Wby action do you have.

Ii probably is a MK V , BUT early on Wby used a number of different actions. I've seen commercial Mausers and Winchesters. Mine is an early commercial Mauser. The reason I asked is that it is really easy to get the wrong bases.

If you end up shimming, I would use stainless steel shim material and make the shim fit between the base and receiver. The mounting holes in the base should match up with holes in the shim, that way the shim will stay in place.

CC, yes it's the elevation. I'm not sure on the action, bought it about 4-5 years ago.
One of the problems generated by the trend to using high magnification scopes is the higher the magnification, the less adjustment in the scope. You mentioned that you had Talley rings and bases. That is who I would contact before launching into an expensive custom project. You may need a base (front or rear) that is a little thicker/thinner than normal. Normally, I would suggest a shim inside the ring, but with the vertical split Talley rings, that will not work. I have had no trouble with the Talley rings and bases on my .358 Win. pistol. They make a fine product, and I have found them to be very helpful at the SHOT Show. Give them a try.

Another alternative, if the Talley route does not work, would be to contact Weatherby. Some years ago, one of the big name gun makers released a batch of rifles, in which the machining was off slightly. This caused an unbelievable amount of problems with scope mounting, I would be surprised if this was the case with a Mark V, but you never know.

Hey bro, try putting a different scope on it first. I had the same problem with my .22 mag rifle and fixed it by putting a different scope on it. I can take off a scope from a rifle I don't shoot often which is a bunch, and see if it works on your rifle. That way you'll just need to send your scope in or get another one. Don't put in any shims, you've been there and done that.

The elevation knob on scope is maxed out upward, with reticle on the bull's-eye of target, the gun is still shooting 3 1/2 feet high.

Turning the elevation knob up raises the point of impact, turn it down to lower the point of impact, ie. if you are shooting high you should be adjusting the scope down not up.

I put another scope on tonight and it is the same scenario. I drilled holes in the shim to allow the screws for the base to pass through them and put the Shim under the rear base. after putting it back on the boresight everything appears to be zeroed now. Off to the range in the morning.


BobT, your right, it was maxed out down.

If you still don't get enough correction, don't be afraid to double the shim thickness. Trial and error time now. Hope everything works for you.

Went to the range this morning , still shooting high. Not as bad, but still I need to shim a little more and then lap.

I've heard of using cut strips of soda or beer cans for shims. What do you guys use?

I always used stainless steel aircraft shim material. You probably can't get it, but the thin aluminum strips cut from cans will do. How thick is the material that you have already used. If you have a micrometer measure it. How much high is it still shooting and how much improvement have you gotten. If I have some numbers, I can probably tell you how much more you need.

Easiest way to do it is put a bore scope on it and start adding shim material until the scope's cross hairs line up with the cross hairs in the bore scope.

I used a pop top inside the ring on my old 30/06 for years. For the past few years, I have been using the wide Dymo label tape inside the rings. It has adhesive on one side, so it won't slip. You can stack a couple of thicknesses if necessary, and it will not mar the finish on the scope. Sort of a poor man's Signature ring. If you need to shim under the base, you can use the metal strips, but a better choice is actual gunsmithing shims. These come in blue, or stainless, and in different sizes and thicknesses. They also have holes for the base screws, so they won't slip. Available from Brownell's Gunsmithing Supply.
