Hoppe's BoreSnake® is the fastest bore cleaner on the planet.  One pass loosens large particles, scrubs out the remaining residue with a bronze brush, then swabs it all spotless with a cleaning area 160X larger than a standard patch.  The BoreSnake® is even machine washable, so you can reuse it over and over again.  A great product to use at home, at the range or at the hunting camp. For Competitors - This is a handy tool to have at the Safe Table!
