What is one of the main purposes of snap caps?

Snap caps are designed to allow dry firing practice safely. This practice involves pulling the trigger on a firearm without any live ammunition being present. The purpose of snap caps is to prevent potential damage to the firing pin or other internal components that could occur with dry firing. By using snap caps, shooters can engage in marksmanship training, practice trigger control, and enhance overall familiarity with their firearm without the risk associated with live ammunition. They provide a safe way to practice shooting fundamentals while ensuring the firearm remains in good working condition.
