Those Outers Foul Out type cleaners are great - and will save you tons of time. One little warning, though: they will get a barrel so clean that, if it is an older gun that has never had a really good thorough copper cleaning, the cleaning may actually expose rough metal in the barrel that has been coated with copper fouling for years.

The barrel will suddenly shoot really bad. After a hundred rounds or so, it will come back around - as the copper fills in all the voids. Not a problem with smooth premium barrels that have been kept clean all along - but then these barrels really don't need the Foul Out treatment to clean them anyway. The ones that really seem to benefit from the Foul Out are regular factory barrels, like Remingtons and Rugers, that are a little rough but shoot pretty well. Particularly with the Barnes X bullets . . . . .
