Custom Shotgun Ranges

If a Custom made shotgun is pistol sized, decrease that shell's base range by 50-90%.

Slugs

Slugs are molded chunks of metal, nylon or plastic. In effect, they turn a shotgun into a crude rifle. Slugs are fired individually, like bullets, instead of in bunches like buckshot and birdshot. They can come in a variety of shapes, but they are often tapered into a bullet shape. They can be solid or filled with substances like explosives or incendiary powder. Shotgun slugs can be rifled -- this is supposed to make them spin in the air and thus improve their flight length and accuracy. One reason hunters use slugs is to hunt deer in states that ban the use of rifles and/or buckshot ammo. The shotgun/slug combination provides a legal, if shorter range alternative.

Shot Rounds

Cartridges filled with shot are the most common type of shotgun ammo. Shot are little balls made of any number of metals, including lead, steel, bismuth, tin and zinc. Each metal behaves a little differently. Lead has some properties that make it one of the most effective materials for shooting game and targets. It is relatively heavy and therefore maintains its explosive force well. It is also somewhat soft, so it changes its shape as it leaves the barrel. This gives it a more spread-out shot pattern than other materials but still delivers a great deal of energy. There is some evidence that because steel pellets do not deform - they maintain their round shape throughout their flight - they wound animals without killing them more often than lead.

Dragons Breath

White phosphorous that ignites upon being shot. Damage and range is the same as Buckshot, ignites target(s) on fire, causes 3D fire damage per round for 3 rounds.

Grenade

Essentially, a hollow lead slug with an explosive tip. It's made with for the purpose of filling with your own explosive or other payload, which then detonates on impact. Impact causes slug damage and range is the same as buckshot range. Secondary effects based on grenade type.

Rubber Round

Two zytel (nylon) balls. High muzzle velocity, very low penetration. Semi-nonlethal, like rubber bullets. Causes Slug damage and uses Slug range but causes stun damage only.

Rock Salt

Rock salt is a popular home defense ammunition because it reportedly causes severe pain but usually no permanent damage. Causes Buckshot damage and uses Buckshot range but causes stun damage only. Useless versus armor.

Gas

Combat shotguns can be used to disperse tear gas and similar chemicals. Use specific rules based upon the type of gas used. Range is the same as Buckshot.

Bean Bag

Bean bags are used as shotgun ammo in crowd control situations, as in most cases they stun the victim but do not inflict lasting damage. Causes Buckshot damage and uses Buckshot range but causes stun damage only.

Breaching Round

Shotguns are commonly used in the military to "unlock" doors when troops don't know what lies on the other side. Because traditional ammo tends to ricochet and may end up hitting the shooter or someone inside the room, breakable "breaching rounds" are often used. These shells contain a metallic powder that disperses on contact. Damage is the same as Slug +1D but range is one tenth that of Buckshot, rounded down.

Flechette

Sabot can also describe an arrow-like shape of material that fits in a standard shell. One particularly frightening sabot-style payload is the flechette. A flechette round contains hundreds of small, needle- or razor-like projectiles designed to penetrate armor and inflict painful wounds. They are banned by the Geneva Convention but do still see use in combat and counter-terrorism from time to time. Damage and range is the same as Buckshot. Modern Star Wars armor does not gain the standard +1D to resist this type of round. Unarmored targets lose 1D worth of natural armor.
