Description

The 13/8-500 patches are manufactured with a high thread count and a tightly woven structure, ensuring they won’t shred or leave fibers behind in your rifling. The double-napped finish (brushed on both sides) creates a “spongy” texture that acts as a reservoir for bore solvents and effectively “grabs” carbon, copper, and lead deposits.

The 1 3/8-inch square dimension is a specific technical choice for the 6mm–7mm caliber range (including 6mm Creedmoor, .243 Win, 6.5mm Creedmoor, and 7mm-08). When wrapped over a jag, this size provides enough material to ensure a tight 360-degree seal against the bore walls, forcing the solvent into the grooves of the rifling. Because they are made of 100% natural cotton, they are chemically resistant to harsh bore cleaners and provide a much higher level of absorbency than synthetic or “T-shirt” style patches.
