How come I can't close thread?
How come I can't close thread?
I had a similar experience with my .223 Axis. However, I am not sure if it was the barrel or the receiver scope holes off. I suspect barrel for me as I think it was also shooting very low. I was too dumb to send it back. I put Burris Signature Zee rings on them and had to use the most extreme adjustments with the inserts. It shoots great though.
I really don't have an answer for you, other than maybe doing something like I did. I am assuming, there is no way to get your money back.
Sounds like the scope base/ring mounting holes on the barrel itself are messed up/out of alignment in some way.
How loose was the barrel in the receiver threads when you installed it? Do you have a 3 wire setup to measure the pitch diameter? Is the barrel obviously off center of the receiver? Had an aftermarket barrel one time that was cut too small and while it would thread, it became canted off to one direction when the nut was tightened down.
Don't have a 3 wire setup and the barrel does not appear to be off center.
I'm beginning to think this is the issue.Had an aftermarket barrel one time that was cut too small and while it would thread, it became canted off to one direction when the nut was tightened down.
Really a bummer when our plans are foiled.
Agreeing with celltech, loose threads will definitely "steer" a barrel off center. One easy check is to compare movement of both barrels with the barrelnut loose. With the reciever fixed measure the amount of side to side movement at the muzzle.
Obvious loose threads will be evident.
I did have one barrel with enough internal curvature that after cutting & crowning it would not zero. I indexed the curvature at 12:00 and ran the reamer in enough to re-headspace and then actually installed a scope with more internal adjustment. Just made zero but was fairly accurate and had the benefit of a 30moa rail with the windage at mechanical zero.
The Burris signature rings will most likely get you there also.
A precision nut & lug may also help if threads are loose.
Hope you find a solution.
