Cleans as dual purpose since it has two diameters:
Reaches further into rifling since it has a smaller gap clearance between bristle tip and bore wall. Makes more patch contact since entire length of jag presses patch fabric against bore wall, makes less rod flexing since bristles flex to accommodate thick patch pleats.
Works with any shape of patch, but our triangular patches clean faster than square ones since our triangular ones have longer radii.
