Maybe I should mine first and see what it does. I am fully prepared to order a new barrel from the CMP. I can see the rifling ok but in the grooves its very dark and pitted.
What did you do to clean yours up. So far all i have done is run a couple of patches down it.

They were 3-5 moa from the factory. Enough to hit a man.

Nothing special. I tried bore paste but it didn't seem to have any effect. I used Hoppes #9 and a bore brush. Swab, brush, swab, brush times a lot in a couple sessions. After shooting I would swab, brush a lot. Of course I haven't seen yours to compare.

Shoot a bunch of jacketed through it and clean it while it's hot. Sometimes that helps.
