Tipton Best Nylon Bore Brush 40-416 Cal 3-Pack

A wide size that spans 40 caliber handgun bores, 10mm, and the 416 rifle cartridges. Lead and powder residue in a 40 S&W barrel gives up quickly to a stiff nylon brush, and the same brush handles a big bore rifle throat.

Thick filament keeps its shape under pressure rather than folding at the first tight spot, and it holds up to solvent soaks that break bronze down. Brass core and stem, three brushes in the pack.
