The barrel needs cleaned right now, I can bore scope it for you. It's had a few rounds shot through it since the Final Finish kit was used and I only used the last three parts of it. My barrel was in pretty good shape when I started. This one is a Uintah 22" made by Prefered Barrel Blanks, they are owned by Match Grade Machine and make some pretty nice barrels.
I don't go overboard on cleaning it now, every time I clean it real good it takes a few rounds to get it to come back to shooting sub .75 groups. I just make sure I get the carbon out of it and get it oiled, and usually check it with a scope every two or three hundred rounds for copper build up. So far so good.
Get you some Aerokroil penetrating oil and some JB Bore Paste to clean your barrel. The JB has a lapping effect on your barrel, and it will remove the copper. Thinning it down with the kroil will help it remove carbon and lessen the cutting effect of the JB paste. You are basically polishing the inside of your barrel.

If you can not see the tyranny of having a gun ban enforced by men with guns... Then you fail to understand why the second amendment was written in the first place.
