Windage problem...Question?

Have any of you ever had a problem with not having enough windage on your scope?.

Here's the problem. I have a Rem 700 stainless action and I have tried 3 different bases and 4 scopes and I still can not get enough left windage to get with in (measured) 6 1/2" of the bullseye. This 6 1/2" right of the target. I am thinking about having a competent gun smith re drill my action for scope blocks (custom).
what's your take on this? what would you do?

Scopes were all 1" tubes, Burris, Leupold, Simmons and a Tasco target. Base were Night force, Leupold and a EGW.

thx for any help or ideas
 
I have not saw this on a remington, but I had a real nice large ring mauser hunting rifle a few years back and the front base holes in the action were drilled wrong and had this same problem. I had a good smith redrill the action for me. Fixed it right up.

This is very common and not just on factory rifles :)

Some simpler fixes include installing Leupold style windage adjustable bases/rings, available from Leupold, Burris, Redfield etc or the Burris Posi-lign system which uses rotatable inserts. More difficult, but still doable, is lapping your rings over using a 1" rod and abrasive compound in a grease matrix. 'Clover' brand is readily available from auto parts stores.



I think re-drilling the receiver is 'way overkill unless you're going with larger 8-40 screws. This is harder than it looks, you'll need a competent 'smith to move the holes over. BTW a competent 'smith could also tell you if it IS the holes..... It may well just be the barrel.

Al, thx for the response. How could the barrel be the cause? I want to understand. It is a new Krieger. It's a 284 just to let you know. This rifle is set up for 1000yd benchrest
smithed by known builder.

thx Joe

I've had barrels 'smithed by known builders that were 'wayy over. IMO it's caused by chambering 'between centers' but I dunno, I've learned to live with it when it happens.

Barrels are crooked. Setups are crooked. ALL of them are crooked to some degree. It is for this reason that I finally got a lathe and am now "indexing" or "clocking" my barrels and pointing them where I want them to go.

No guesswork this way

-6.5 inch's of windage is alot. I would do some very serious checking before tearing into anything. If it were to be the screw holes' for the base mounts', which one's? Front, back, or both. How are you trying to zero this rifle, such as, how are you holding it?

Thx for your input. This is at 100yds. off of a 45lb rifle rest and rear bag. not sure if it is front or back or both. I had 2 other shooters with me try it also. it printed almost the same.
I am at the end of the travel for windage. no more left. I put one of the scopes on my 30 br and it went back to almost center of travel. So i figure the scopes are not the problem.

Thx Al I think clocking is a good idea and I have one barrel that is set up that way.

I have a rifle, not a Rem, that was off about 3' at 100 yards. I'd forgotten about it when the rifle was rebarrelled by a man who knows his business. The thing was still off 3' at 100 yards. The two easy solutions are as Al says either Leupold bases with windage agjustment in the rear base or Burris Signature Rings. The only problem with the Burris Signature rings is that they are scarcer than hen's teeth. I had a set on backorder for several months, and ordered another set, and they're backordered as well. Supposedly they'll be in sometime in February 2012.

It's likely that the screw holes for the scope bases are drilled out of line with the centerline of the action or that the face of the receiver is way off from 90° to the action centerline. If the rifle shoots okay except for being unable to adjust the windage it's likely that the base holes are out of whack.
 
How did the rifle shoot before the muzzle brake was put on. try standing back from the rifle, and check the relation of the scope to barrel straightness, or lay a lenght of tubing in the lower rings. Something just sound's way wrong here.

Larry, Thx for the help. I have about 4 sets of the Burris rings. And I have numerous Leupold bases. The rifle shoots very well. No joking it shoots. I need at least 15moa to get on paper at 1000yds in elevation.
thx Joe

B It shot right in the same group as it did with it on. I will do that with the tubing and reply. I agree this is very puzzling to me also. The only rifle I own that has had this problem.
I have had around 50 rifles for shooting targets and game.
thx Joe

Have you had the action threads trued up with a lathe or just chased with a tap. Randy

Randy, I pd the smith to true it up and chamber it for me, so I have no way of knowing. But I feel like he did. I do not think he would have done it any other way.
Many a good questions have been asked all will be checked and what I find will be posted. I am still up for more info. to the possible causes.

thx Joe
 
The reason I asked is that my ex-smith told me that chaseing the threads with a tap was good enough.He faced the reciever ,the lugs and the backside of the bolt lugs. I am having the same problem with a Model Seven action. You can look down the lenght of the barreled action and notice the scope mount threads hole look true to the action but not to the barrel. His fix was a Leuopold windage base scope mount. The scope looked funky being canted on the rifles reciever in trying to line up with the barrel. RANDY

Randy, Thx for the reply. I will question him on this. And yes the holes look like they are in the center with the eyeball looking at it. If I knew what they should measure, I would measure them and see. And who would you now recommend for fixing this. I did not put all this time and money in having it built to have to re-engineer it with an awkward looking setup.

thx again Joe
 
OK, this will sound silly, but it's actually sound.

With the rifle fully assembled lay a long (36-48") aluminum rule against the left side of the action extending out past the muzzle. With a caliper measure over to the barrel.

Do the same thing on the right side.

Check the muzzle for obvious eccentricity or measure to the bore. A fitted pin would be handy but not required. Either way an obvious misalignment should be easily measured. If the action threads and action face are cocked to the action centerline this should point it out.

Al, this sounds fine to me..good idea... I will do that tonight after work. And if it is, who would you recommend of all the good smiths we have to fix this problem?
