Pepper balls are typically available in three calibres: 68 calibres, .50 calibre, and .43 calibre pepper balls. The .68 calibre pepper balls are considered the most common and have a larger diameter and weight than the other two types, making them better for long-distance shooting and the strongest pepper balls. In contrast, the .50 calibre and .43 cal pepper balls are more suited to shorter distances and less-strenuous environments.
