A shotgun, also called a "scattergun", is a firearm designed to shoot a multitude of lead or steel balls of varying sizes. This makes it very effective at hunting game, greatly increasing the weapon's hit potential. However, the accuracy and power found at close range diminish rapidly as you get farther away from the target. Shotguns designed for military use are often called "combat shotguns".
This weapon is an "over-and-under" shotgun with a pattern/logo cut into the stock and an engraving of two birds on the frame. Despite its rough appearance this caravan shotgun is extremely durable, with more than twice the item health of a normal caravan shotgun, hence the name. There is some sort of tally mark scratched into both the back of the gun and beside the trigger. The gun is duct-taped at its butt and at a crack in the wood closest to the barrel.
This gun is significantly more durable than a standard caravan shotgun, but somewhat less accurate. If your repair skill is high enough to make the added durability unnecessary, it may be worth going with the standard version instead.
