Piercing shotgun shells

Piercing shotgun shells is an item in the ammo category and ammo subcategory that functions as shotgun ammunition; it stacks up to 100 in an inventory slot and is consumed by weapons and turrets that use shotgun-shell type ammo. It serves as a specialized shotgun-round item within the game's ammunition system, occupying the same usage slot as other shotgun shells and interacting with crafting, logistics, and combat mechanics that handle ammo items.
