Pump-action shotguns are a classic niche, but not as diverse in terms of equipment as conventional small arms because of this, convenient 12-gauge pouches are rarely found.   

The "Shell" pouch holds 12 rounds of 12-gauge ammunition. The cartridges are arranged in two blocks of 6 cartridges, which are attached to the outer Velcro of the pouch. After shooting all the cartridges from the first block, this block is unfastened, and the second one is put in its place.   

Cartridges are fixed with tight elastic bands, which prevent their loss.
