How do they work?

When the gun is fired, the pressure and the acceleration of the felt pellet causes it to shrink in length and expand in diameter to the desired high friction, allowing the felt pellet to press itself into the rifling and follow the twist. This ensures that every part of the barrel is reliably cleaned.

Ideal to carry with you for the last shot of the day, to quickly and easily clear the barrel.
In order to prevent fibres remaining in the barrel, it is recommend that you insert a pointed lead pellet behind the felt plug and shoot the two together.
