We all know how fast copper fouling can ruin your accuracy.I alway try to break in a new barrel buy firing a shot and cleaning. Repeating the procedure for a number of rounds. It seem to help.Some barrels take on copper much worse that others.I have used a number of product in the past with marginal luck. Most of them contained ammonia.I have also used JB compound.So I was just wondering what everybody else is using these days and what luck you are having removing copper fouling.
Thanks for your input.
