Fido... Yes, I use a nylon brush on the end of a flexible rod & push one slightly dampened (50/50 prestone or 10% water souluable cutting oil) 2" arsenal patch (you can buy them from Buffalo Arms) through once- pushes out 98% of the fouling & tends to keep the bore cooler when laying out in the sun on the 1000 yd. line. Good luck, it is challenging finding the 10 ring consitently at those distances... Dennis
