Yes, I did have them off the rifle when changing the barrel. But these dual dovetail rings have the eyeball-like bushing inserts that allow pivoting, eliminating any chance of misalignment.OP, did you remove bases and rings when changing barrels? Of so, any chance you did not get the rings lined up truly perpendicular to the bore and inline with each other before clamping the scope in place? Dual dovetail rings can cause zeroing issues if not lined up; also puts stress on scope. I usually mount this type with a round bar of correct diameter. When the bar lies flat in the bottom of both rings, they should be aligned properly. Just some more guesses as to the source of the problem.
The dual dovetail bases and rings don’t use the common “cross bolt” lockup like regular rings. They use a camming action to lock the ring into the base, when turned into position.How much torque on the nut?
Apparently the .222 barrel shot just fine when he had that setup on the rifle. Then he switched to a cheaper, do it yourself, remage setup that was done on a production line somewhere (just like a factory setup) instead of having a good gunsmith put on a new barrel. I can see what's wrong with this picture.

I’m sorry Frank, I misunderstood your question. I put 50 foot pounds on the barrel nut.I was asking about the barrel nut torque.
I used Northlands action wrench, that Has a special attachment that holds the recoil lug in place as you tighten down the barrel and night. No pins were used.How did you install the lug? Pin it to the receiver or unscrew the pin and use a centering tool?
Well DoneI used my new laser cartridge and confirmed that impact was WAY off to the left, just on the wall inside my house. I then removed the scope and took both rings and bases off rifle. I did the straight edge trick, looking for a crooked barrel, using 10at6's and Msalm's thinking. Doing that, and closely observing the free-floating barrel's clearance down the stock, everything looked true. I installed just the four mounting bolts in the receiver and aimed them at the wall while the laser was projecting down the bore, at the wall. Thank God they lined up laterally! I spun the front base 180* when I installed it, (thanks Alton9), just to try something, and installed the rear base as before. I put the windage knob on my scope in mechanical center and remounted the scope and torqued all bolts down to Burris's specs. When I used the laser on the wall, the red dot was EXACTLY on my vertical crosshair of my scope. I am elated! Honestly, there were so many variables, (as a couple of you stated), that I don't know what was wrong. Now, I need to go to the range and verify with live ammo and continue breaking in the new barrel. My fingers and toes are all crossed hoping that I corrected this problem. Thanks to everybody for your help and suggestions. I do appreciate it!

That shouldn't have been too much. I have only done one. Didn't use a torque wrench because I could not find a consensus on all the forums I visited. Snugged it up by hand and gave the wrench a couple raps with a rubber mallet. Still tight after 600 rounds. I am a precision kind of guy. That went against the grain a little. lolI’m sorry Frank, I misunderstood your question. I put 50 foot pounds on the barrel nut.
