Someone has to fixture the receiver in the holding jig prior to. It may have been a Monday morning at 8:05AM....lol

Re: misaligned reciever holes for scope

A reciever face out of square by .001 causes the barrel to be "off" by.00000174xx

which will cause a prefectly true barrel to put a bullet .628 from where ya want it to go at 100 yards.

And people....001 of a degree aint much at all!!!...

Re: misaligned reciever holes for scope

It could very well be his reciever face needs squaring...But my money is still on misaligned holes. And I rarely see an older model Remington with misaligned holes or an out of square receiver....Especially recievers from the 60's to the early 2000's...That was back when Rem still had good QC. My Sendero SF is proof of that. That gun is a 2002-2003 model and it has been stacking 1 ragged hole groups since it was new.

Then again, my 2011 model 700 5R .308 also does the same thing, but I've been told those, like all Rem's higher-end lines, are put together and fitted by hand by master gunsmiths, vs the mass-production factor.

If his gun were a newer model ADL Wally World or Academy special, I might be a bit on the concerned side of things about the misalignment or out of square receiver, especially since those rifles are the factory seconds, that couldn't pass the cut as a BDL or CDL... Which for $379.99 makes them an excellent candidate for chunking the barrel & stock and starting a custom build on them, where you are going to true up the whole reciever anyway...

Good plan. When I said to "chuck" the Tally rings, I really meant replace them - temporarily. Now that you've bedded and lapped the Tally rings, the only issue with them is that they aren't windage adjustable, which is what you need for a temporary fix.

After you get the rifle back from the gunsmith, you may find that the Tally's you have are boresighted just fine. If not, then the receiver holes were at least part of the problem. Your gunsmith will sort all that out for you.

I'm thinking the same thing here. On the positive side, if the holes aren't WAY off, a good smith can open the screw holes to 8-40's & center them at the same time (I had this done on a 700). Chad didn't have to fill the holes first, then again, he didn't use a drill either. All of 20mins of work, the wonders of CNC I guess.

I wouldn't drill them either though CNC is not required other than extrapolarion of the original bore location. I'd use a centercutting end mill myself. That way, the bottom of the hole remains flat.

I'm in the middle myself of a similar scenario with a firearms manufacturer.
