Been pretty lucky so far.

That's good you are happy with the gun. Most of the problems with accuracy from what I have seen and read was paint in the ends of the barrels. Try not to have too much fun you don't want to use it all up and become a bitter old man. ;^)

Yes, don't be bitter, be a curmudgeon. It's much more fun and you can start early. And the pay-off for your skill level only grows.
 
I'm LOVING the gun, I haven't actually checked the barrel for paint, but with groups like this, I don't think it's an issue.

This is a 6 shot group at 20 yards, ignore the flier it was my fault.

The center circle is 1 inch.
 
Just like was already Mentioned.Yes a lot of them came with paint in the barrels. Mine did and had to use paint remover. I tried paint thinner and wouldn’t work. But just put a little bit on the tip of a model brush and left it on there for 15 minutes and then took a Q-tip and cleaned it out. Groups shrink right up.Yours might not have paint in the barrel though because I don’t think you would get those kind of groups if it did.
