The Thompson/Center Muzzleloader Cleaning Patches are all cotton, general purpose, dry cleaning patches for cleaning your rifle or pistol. These 2 1/2" patches are specially designed for use with .45 to .54 caliber firearms. However, the patches can accommodate a variety of calibers and gauges by offsetting the patch position on the jag, centering the patch, or doubling the patch thickness. These general-purpose, dry patches can be used in multiple ways, and come ready to use in a 100-count pack.
