If you own a gun and you don't own a BoreSnake, go get one now! This is the most effective tool for cleaning out the inside of your gun barrel.
The BoreSnake brushes and swabs the bore in one quick pass. Multiple short brushes embedded in the floss; they pass easily through the shortest action or port. Initial floss area (inside the barrel) removes loose grit and debris prior to the scrubbing action of the brush. Main floss, with 160 times more floss than a patch, supercleans the bore. Basically lube up the snake, drop the weighted cord through the barrel, pull it through and you are done! I've had mine for a few years now and it is the only way to go! Hoppe's has BoreSnakes available for most popular guns from shotguns to rifles and handguns.
