Some barrels will clean up in 5 rounds. Some take over a hundred.

This barrel is close to 300 now

It seems you just got a bad one. I would call the barrel company. Or more correctly to your smith. He will have history with them. I do not think this is any of his fault. You can,t make a silk purse from a turd. Every barrel maker gets a bad one slip through sometimes.
