Dewey bore mops are made from 100% cotton with solid brass twists and cores. These mops are used to apply solvents or rust preventative agents to the bore. They can also be used to remove excess solvents in lieu of using several patches. They can be cleaned and used several times over. The larger sizes are great for swabbing out chambers.
