I have a good gunsmith and I like that option. I would have the action blueprinted. Right now have the following barrelon some rifles
Lilja,Kreiger,Barlein,Lawton,Broughton,Rock Creek,Obermeyer,Chanlynn,Hart,K&P,Shilen,Gaillard. I think Brux and Benchmark and couple others make a good barrel.
I'm not buying anymore barrels and this includes Shilen that make different grades of barrels like super match then they have a match etc.
Option on finding a gunsmith you can call Mike Rock,Dan Lilja,Kreiger etc and say your interested in having one of the barrels put on and could they give you a name of a gunsmith in your area or close by.
One problem with the barerl guys chamber is custom throating or changing to a Wyatt magazine box give you little extra Seating depth for the RUM or you may want little heavier recoil lug. I just as soon talk face to face.
