One of the biggest obstacles to competing successfully in the most popular 3-gun equipment divisions has nothing to do with actually shooting. Rather, the ability to load a shotgun quickly and on the move is often what separates the winners from the also-rans.
Cramming rounds into a tube-fed shotgun is a time-consuming exercise, and the ability to perform this task without dropping precious shells can decide where you place in the overall standings. Usually, this calls for a weak hand reload, where the shotgun remains shouldered while the left hand grasps three or four shells from a belt mounted caddy. These are then thumbed one at a time into the loading gate, a process which requires a lot of practice and manual dexterity.
Carbon Arms has stepped in to help solve this problem with products include multiple shell holders “that allow the use of loading two in shotgun at a time” and are designed for ergonomics, speed and reliability.
