Actually , the copper protects the barrel but it effects the accuracy and consistency.
The factory always leaves the copper in the barrels after test firing to prevent
rusting in shipping and storage.
Someone said shoot until accuracy falls off and then clean and "Start all over". if your rifle is
shooting just over a half minute fouled it can do better cleaned up and with the right load.
With a clean barrel you dont have to start all over and shoot lots of rounds to get accuracy back
It will shoot it's best for the first 4 to 6 rounds.
