I have two that were taken apart and put back together. New trigger, Action trued, One had a new lug installed.

Results: 1 did very well with same load as before any work was done; the other is a complete scratch and start over. The second one went from half to maybe sub half moa to a 1.5 moa rifle after being put back together. I did not do any of it so I dont know if anything was done differently between the two. Strangely, the one that is shooting the best, the barrel is in a different relationship to the action. I can tell because of the paint job I had done and now there are some unpainted areas exposed on the barrel. Dont know if any of this is helpful, just my experience.
