Not enough adjustment to zero rifle

[schwanman]

I recently purchased a Browning Long Range McMillan in 6mm Creedmoor. I mounted a Leupold VX6-HD 3x18x44 on it with Seekins Precision rings. I already comes with a 20 moa base. Took it to the range to sight it in and with my elevation as low as it will go I'm still 4.5 inches high at 100 yards and my right windage is gone and I'm still 1/2 inch left at 100 yards. I haven't tried a different scope yet but I don't think the scope is the problem and I haven't tried a different base because I don't have one. I've swapped the rings front to back and have turned them around so screws to mount them have been on both sides of the scope and it shoots in the same place regardless of the configuration of the rings. Any suggestions? The rifle shoots great but doesn't do me much good if I can't zero it.

Do you have another scope to put on just to see where it hits? Rail would be the next culprit. Then the action may have been drilled out of square.

I'm going to give that a try. I feel pretty good about the scope but I'm going to try a different one once I get some decent weather and a little time. Since it got me back to the same place after removing and trying different ring setups I have my doubts whether that could be the problem but I know that's the next step just to be sure. Just thought I'd see what other suggestions people have that I could try if it's not the scope.

I had a Remington 700 that ran out of windage adjustment. At 100 yards it was about a foot to the right. The scope mounting holes were drilled at an angle across the action so much that you could see it with the naked eye.

It sounds like you have two potential problems. The left to right is likely due to either the rifle base holes out of square with receiver or the base itself has the mounting holes out drilled out of square. The elevation is also probably due to a combination of the 20 MOA base and your ring height. Easiest cure is change base to a 0 MOA and if Left to right is still off, then get a set of Burris Signature rings and with off set inserts then square up scope to bore by playing with the +/- ring inserts. I would definitely not think the scope is the problem based on what you have stated. Good Luck.

As info mine was fixed by Chad at LRI by offsetting the bit and drilling the mounting holes out to 8-40.

Remove your turrets and then adjust your elevation. I had the same elevation issue with the vx 6hd 4x24 and a 20 moa rail.

I was just fixing to say, I'd check the rail, and then also the scope mounting holes. If they are not straight, and are REALLY bad, you can have a gunsmith fill-weld the old ones in, and re-drill and tap new ones. Or, if they're just slightly off, he can just open them up to 8x40 screws to cut the excess out of the wrong direction, and that should straighten everything up.

Agree with Rob D. Sounds like your scope is preventing you from dialing in due to the special turret caps. According to Leupold site your VX-6 HD has a zerolock. From Leupold pdf file I found on line:


If your Leupold riflescope is a model with CDS ZeroLock™ adjustment dial, you must push inward on the lock release button located on the outer edge of the dial above the zero indicator mark to make an adjustment . Once the dial has
been turned one or more clicks past the zero position it is no longer necessary to press the lock release button . The CDS ZeroLock adjustment dial will only lock when at the zero position of the dial .

When I mount a scope, I also check to see if the crosshairs are centered in the adjustment range. mtmuley

There is another potential problem. On two rifles it would not hit a 2'X4' board at 100 yards. I looked through the bore again to verify the bore sighting. This time I looked a little more critically. The bore was oval shaped rather than round. I discovered the barrel was bent. Another time the 'smith turned the tenon threads at a slight angle. We discovered the bore was not inline with the action.

Make sure your 20 MOA base is mounted so that it's higher in the back than the front. Mine was installed in correctly at the factory. If you scope has zero stops you need to free them up before adjusting.

As an exercise to test if it is the zero lock before pulling out the tools again, it is easy enough to test the full range of adjustment by counting revolutions lock to lock. Quick googler tells me full range should by 75 MOA for that scope.

As stated above, you may be hitting the zero stop on ur scope. Also, I would check that base or replace it. Something is definitely up that you ran out of windage
