Thompson Center Lubricated Round Ball Shooting Patches 

The Thompson Center® Lubricated Round Ball Shooting Patches are designed for use on .45 or .50 caliber rifles. These pre-lubricated shooting patches are 100% cotton, come in uniform thickness of .015”, and designed specifically for traditional round ball muzzleloader shooters.

The T/C® Roundball patches are tightly woven and totally resistant to burning. These 100-count, lubricated patches are for use with a round ball of approximately .010" less than caliber. As an example, a .50 caliber rifle uses one of these patches with a .490" diameter lead ball.
