Remington M700 KS Mountain rifle. Scope mounting troubles

[olekiwi]

I have a Remington M700 KS Mountain Rifle in .22/250 with Burris XTR 2-piece bases and Burris Signature Zee rings. Scope is a brand new Leupold VX3 4.5-14.

I'm assuming the scope is factory centered. Anyway, my first shots at 25 yards are 10 inches low!

I have wound it up a heap to zero it at 100 yds, but I'm wondering should I be fitting 20MOA PosAlign offset inserts to the rings to lift and re-center the scope, or would I be better to fit a 20MOA rail?

Have yet to pull off scope to check base alignment but I presume this is where the problem is?
Any advice gratefully received before I go any further with this.

Throw the Burris junk away & install a std 1pc or 2 pc base(s) on the action.
Center the turrets on your Leupold 4.5-14X.
Mount the scope/bore sight & zero the rifle.

You don't have the correct Bbl twist to shoot heavies out of your 22-250 so a tapered base or rings is a waste of money.

if you have the burris rings with the inserts you probably need to change out the inserts or move the top half ring insert to the bottom...imo these rings are the best made..i personally wouldnt get rid of them...you just need the correct insert thats all.

I would pull the rings off and start with the "0" inserts and shoot it with them in there and see where it lands with the scope turrets recentered...if it needs large amounts of adjustments then insert the other inserts to move scope tube in the direction you need it

probably not the scope or the mounts. The last two Rem. 700s had the face of the action so far off from true that I couldn't hardly get enough adjustment from the scope to hit paper at 100 yards. A fellow here won a 700 in a gun bash and showed it to me recently. It didn't have a set of mounts on it yet. I sighted down across the mounting screws looking at the muzzle. It had to be almost a quarter inch out of line. Showed it to another fellow there and he couldn't believe it. Just my experience your mileage may vary.

First check if the barrel has contact with the stock. If yes, remove material - the barrel should be free floated.

If this doesn`t help, buy "shimps" and put it unter the base to correct it.

I also suggest to glue the bases with good 2K epoxy.

I have not used Burris bases, they may or may not be your problem. The machining of the action and barrel could also be the problem. Since you are asking the question, which is certainly a good thing, I am guessing that you may not be comfortable with the shim remedy. I vote with the ones saying to keep the Burris rings, center your scope adjustment, and find the combination of Burris inserts that will get your POI correct. There are other good solutions, but they are a bit more time consuming and complicated, all of which may be beyond your needs for a hunting rifle? I am confident that with all of the advice on this forum you will get this project on track!

you're making way too many assumptions, and the notion that you didn't bore sight this rifle first and then ensuring the scope is adjusted to match makes me wonder if you've ever had a rifle before. It's always easy to blame the gear rather than the shooter.

The brand of gear doesn't matter, nor what it cost you. It's about BORE SIGHTING first, and always, when you're setting up a bolt-action rifle. It's so easy, and yet so many shooters skip this step. 8)

I agree with Nate Haler on the bore sighting. I am also in the assumption mode here. You don't need a bore sighter tool. If you do not have a "gun vise" of one type or another, you'll need to use a rest that can hold the rifle stable. With the bolt removed, sight down the center of the bore onto a target or facsimile thereof. When you are "bore sighted", look through the scope and it should be close to where you sight picture through the barrel is. If everything is close, you are ready to go to the range! If you must move the scope adjustment to an extreme, either find and correct the problem, (if this means remachining, you obviously cannot reasonably correct that) or use the Burris inserts to bring the scope back to center.

I personally dont feel we should insult anyone asking a valid question whether new to the sport or not a kind answer ought to do it.Remember we all started with lack of all knowledge to what we know now.

+1 Hope you were not referring to my posts. I'm just trying to help a fellow in need of some answers.

What has worked for me is: Take a 1"square of florescent paper and attach it to a tree, building, something stable. Set your rifle 25 yards away on anything steady with the bolt removed. Adjust the rifle until the florescent square is centered in bore of your rifle. It takes a bit of patience to be sure it's centered and stable. Once your happy touch nothing and look through the scope. What you see is the difference between the scopes cross hairs and the point of impact. Patience is the key.

+1....could not agree with you more.

Assumptions in our sport are dangerous. Sure, some are more ill-advised than others. But ours is a sport where tough love clearly has a place. Assuming a scope is centered at the factory... Assuming that the handloads you bought online are safe in your rifle... Assuming that a firearm is unloaded...

I suffer permanent and significant tinnitus in both ears because of assumptions made by other shooters. One my brother (who thought I didn't see a rattlesnake some 15y in front of me, as we walked on a ranch, so he cut loose from behind me with an AR15). Another a gunsmith's brother, who triggered a 2" .357 mag round into his own foot while standing a few feet away inside a steel building with concrete floor while the gunsmith and I conferred over my Remington 572 Fieldmaster. He assumed the gun wasn't loaded. For more than TWENTY YEARS my ears have rung, and will never stop.

And maybe some of you have burning ears at some of the comments made on this board, and how frank some of these comments are. But ours is a serious sport. Serious fun, with serious and permanent safety considerations.

If you don't understand how this stuff works, then ASK before you go out and possibly endanger other people. I watched in a amazement as a friend of mine was hit in the face by a splinter of a bullet from the guy shooting in the next lane because he was shooting at a rock instead of the target. Sight misalignment, or just plain stupidity, or somewhere in between.

So many of the newer shooters get caught up in what they're buying instead of WHAT THEY'RE DOING!!!

My local range was closed for more than THREE YEARS because some yahoo launched a bullet over the hillside beyond our target line, and supposedly penetrated a barn roof half a mile or more beyond. Do you think that negligent schmuck deserved to be coddled, or should it have been his job to understand WTH he was doing before committing an act that had consequences that affected hundreds and hundreds of other shooters in the area, and cost the range multi-thousand dollars in lost revenues.

If the new crowd, and some of you enablers out there (you know who you are), would spend even 1/4 of the time considering basic rules of firearms and sight function and safety and consequences, vs. agonizing over whether to get a Leupold VX2 or a Vortex BFD, or whether Savage is better than Remington, then we could all benefit.

Rant off.

Greatly appreciate the replies...and quite take the point about "assumptions" which was why I was asking about options before pulling the scope off and starting again by carefully rechecking things.
I would normally boresight before heading to the range - particularly if the mounts being used were windage adjustable. In this case they're not (except via the PosAlign inserts). I'm no newbie but have limited access to a range and got this set up rather more quickly than I ordinarily would to start some load development. Most certainly boresighting would have identified the issue at home, rather than at the range.

I will recenter the reticle in the scope, take the mounts and scope off the bases and run a straightedge over the bases. If there is a discrepancy between front and rear base heights I guess I have the option of shimming to level them up; or using the inserts to compensate; or using a +20MOA rail to compensate. I still have vertical adjustment left in the scope but the scope is obviously not optically centered which is not ideal. My preference would probably be to use the inserts, but I'll try to establish where the problem is and report back (probably after the weekend).

The gentleman asked questions about scope alignment, not safety! As I see it you insulted his inteligence and then just made a windy justification, allbeit off topic, for doing so. Hope you feel better about it now?
