How can you clear a breech plug?

Clearing a breech plug typically involves using a method that effectively removes obstructions or residues that may hinder the firearm's operation. Snapping a primer is an accepted method as it can help release any remaining pressure in the chamber and dislodge any debris or obstructions that may be affecting the breech plug. This action creates a small amount of force that can clear minor blockages without needing additional tools.

Using a cleaning rod is generally intended for cleaning the barrel or other parts of the firearm but is not the most effective or safest method for clearing a breech plug specifically. Pouring water through it could potentially damage the firearm or lead to rust, as moisture in the wrong locations can create long-term issues. Disassembling the firearm can be cumbersome and unnecessary for simply clearing the breech plug, as it involves more steps and may not be practical in every situation. Hence, snapping a primer is the most direct and effective means of addressing the issue with a breech plug.
