here is the problem I ran into, I mounted leupold Dual dovetail mounts on a rem 700 sps, then lapped in, put on a new vx3 4.5x14x50, using leupolds bore sight tool I just found that I do not have enough windage adjustment to bore sight, I simply ran to the end of the windage adjustment range and it is not where it needs to be. So anybody have the solution?
I used the dual dovetail mounts 2 pc for rigidity....wth??
experience needed on this issue...
 
welcome to THR

leupold's sight tool is kinda neat (the magnetic thing you stick on the muzzle) but it's not as useful as actually bore sighting it, in my experience.

If you're out of windage, you should be able to just look at the scope and see it is obviously not straight. assuming it doesn't look wrong from the outside...

bring the scope back to mechanical zero. (run it all the way to one side, count the clicks as you run all the way to the other side, then go back half that number of clicks)

pull the bolt. prop the gun up and look down the bore, then look through the scope without touching the gun.
 
Another thing is that it's supposedly not unusual for the mount holes to be drilled in the receiver crooked. I don't think that anyone has mentioned it here, but I've read it on other sites. I know that mine isn't straight. I don't know if I want to send it in to remington or just live with it. I don't know what I'll get back. I used a Leupold "Standard" base that allows you to adjust windage on the mount rather than eating up the range on the scope.

So, either the tool is wrong or the holes aren't drilled straight. For you, I hope it's the tool.
 
definitely try different bases and rings. I think the Leupold standard windage adjustable rear or the Burris signature offset inserts might help. Maybe both?
If you can't get it centered, send it back to Remington or trade it.
 
I have been using the laser bore sighter for years, works great! I have heard about the crooked holes on the Remmys, and the windage adjustable bases are a good solution, as well as the siganature rings, I have experience with both, and am pleased with both. If you wanting to stay with DD rings and bases, Signature is the way I would suggest, no lapping needed, a little more of a challenge to level your scope, nothing you cant handle though. When you get the Sigs mounted, they will be rock solid! Best part about Sigs are, you can keep you scope as mechanically zeroed as possible while your bore sighting, and even give your self a little offset for more elevation adjustment.

can you mix burris dovetail rings with leupold bases with sucess?

That's not recommended as a) they may not be the same height, and b) that wouldn't solve the problem if the receiver holes are misaligned. Besides, you would have undone all your lapping work.

You can check for misaligned bases by using a steel framing square.

Put the gun in a cradle or shooting rest; remove the bolt and place the short edge along the back of the receiver (where the bolt was), and try to line up the side of the bases with the long edge of the framing square. If everything lines up, the receiver was drilled and tapped correctly.

I suspect that the boresighter is misleading you. Put the gun in a cradle or shooting rest; as previously suggested, move the the windage back to the center of adjustment, remove the bolt from the receiver and see if the bore and scope are looking at the same point of reference.

The solution to your problem is a set of Burris Signature Zee rings. These rings have polymer inserts in them, and you can buy offset inserts that will point your scope in the right direction. While I have never had the problem you have, I use these rings exclusively on all my hunting scopes.

thanks for all of the input.
1. I am going with burris sig rings and bases
2. Rem factory service is terrible
3 leupold was helpful in providing needed info.
4. if this does not work I will dump this rifle and go with another brand as this is what I have done so far.....
rem700 sps (308),added a timney trigger, a calahan firing pin assy, added a hs precision police sniper stock, a leupold vx3 4.5x14x50 now going with burris rings and bases and still have not made it to the range...
needless to say I am po at this situation as I have invested heavy in this rifle as well as ALL of the nessasary gunsmithing tools needed to mount scopes, etc. with no satisfation yet???
 
I'm not convinced that we've established that the holes as mis-aligned yet. Did you get a chance to actually visually line the bore up with the scope? Over the years I've had much better success that way.
 
Man, I'm not suggesting getting rid of the rifle even if the holes are off center a tad. I went with the Leupold setup and it's rock solid. The reason that I haven't taken it in to see about sending it back is because I don't know what I'll get back. My SPS shoots very near 1/2 MOA with several different loads and I don't want to risk losing that.
 
I agree with everyone here, I wouldn't send it back, I would put the rifle in a padded vise and bore sight it looking through the bore, it might just be the boresighter is misleading you, use the square and check for alignment, and I read somewhere that you could have a gunsmith re-drill your holes for a beefier mounting screw that is also closer to be being perfect than a factory job. You might have a real good shooter there. I have Millett rings mounted on both my Leupold bases, no issues at all, so I dont see why you wouldnt be able to use Burris with Leopold. Hang in there, we are all pulling for you!!!

+1. I have a streetlight 120 paces from me that is perfect for this;It is how I have bore-sighted my last 6 mounts. Just be sure to do it at night, and BE SURE TO DO IT FROM A DARK ROOM.

This is the kind of thing your neighbors might take a dim view of.
 
I know lots of guys who use dovetails, but I am not a big fan of any scope mount the turns into the base.
 
waiting on burris rings and bases, i will post an update when I get them on, I do have Alll of the nessasary tools including a Tipton premium gun vise, so I WILL do the actual bore sight method, but one note here is that I have both versions of the Leupold bore sighting tools of which the older version has mounted several leupolds and was verified against the newer version both were the same after careful setup and check, recheck.
NOTE: Remington will not assist because I Voided the warranty when I installed the Timney...LOL..what a crock.

I will tell you all that after all of this and this rifle does not shoot, I WILL NOT BUY ANOTHER REMINGTON EVER.

You didn't get carried away with the 'lapping' did you...?

IF That proves to be the case after the new rings arrive ,There will be a wheeler complete laping kit for sale....cheap....lesson learned...and I have considered this may be the case, but we shall see.
 
DD turn ins can be a craps shoot, especially for those not at gun smith level. I've found that the era of the 1913 standard has made my gunsmith a poorer man. With a one piece base and a good set of rings the only factors left are level and torque. I doubt the factory drilled hole would be drilled so far off as to run you out of windage adjustment.

The other nice thing about a rail is the option of mounting other optics JIC. My dad learned that lesson recently when he dropped his $100 scope on to my tile floor a week before deer season. Luckily I convinced him to rail his TC and use quick release rings (which cost more than his lousy scope). I swapped out my Sightron SII Ill. and we had a great hunt.
 
Have you shot the gun to see if you can adjust the scope to your target? I have had several guns that were way off target after boresighting, shooting prove to be the correct way to go.
 
Thanks for the info guys. I just ordered the Burris dual dovetail mounts and signature rings (with insert kit) for my SPS Tactical. I'm not sure of whether the dual dovetail is strong or not, I've never used them; but I really like the clean looks and as far as I'm concerned, the fewer screws to come loose the better.

Just a note about how off center the mounting holes can be, when I had my scope mounted in a non adjustable mount, I had to use of 50 clicks of my available 64 to get the windage dialed in. I was using the Leupold standard mount to take care of this, but I'm not crazy about that system of adjustment.
 
burris ring inserts....that is actually the right way to do it. When in doubt...shim it.
