If you're new to the game and shooting sub Minute at 400yds, you're doing nicely already.
As a rule, and I know many others disagree heavily with this, but if a barrel is shooting well for me, I don't touch the inside of it. Shoot the **** out of it until accuracy falls off, then scrub it down and start all over.
A very wise man once said, "Barrels are a lot like p*ssy, in that guys flatter themselves in thinking they can hurt one."
Have fun and shoot a lot!
