I have an Adams and Bennett .308 barrel on a Yugo Mauser. So far it has 100 rounds through it. When it is squeaky clean, it shoots 1 hole 5 shot groups at 100 yards. However, it fouls badly and quickly. After 5 shots the bore looks like a shiny penny. Only an overnight soak with Wipeout will remove the fouling and restore accuracy. Needless to say, I would like to shoot more than 5 shots when I go to the range. What do all you guys think, should I use Final Finish to remedy the fouling situation and, if so, how many rounds should I use as this barrel is neither a "factory" or a high end, lapped at the factory barrel?
