Tipton Best Nylon Bore Brush 20 Cal 3-Pack

A 20 caliber bore sees a lot of hot varmint loads, and a 204 Ruger throat cakes up fast. This nylon brush takes the scrubbing without putting bronze against the steel of a match barrel.

The bristles are thicker than what you get on a bargain nylon brush, so they push fouling instead of folding over at the first patch of hard carbon. Brass core, brass stem, three brushes per pack. Nylon also survives ammonia copper cutters, so the same brush goes back in after a solvent soak.
