20 Gauge Round

20 gauge shotgun shell is a type of ammunition in Fallout: New Vegas.

Characteristics
20-gauge shotgun shells are very similar to their better known cousin, the 12 gauge shotgun shells. 20-gauge shells are a plastic tube with a brass base. The primer, gun powder, and wadding are compressed into the bottom of the casing and the projectiles are placed on top, held by the plastic tubing. Most common projectiles are small lead or steel balls called shot. Being smaller than 12-gauge shells, 20-gauge shells include less powder and less shot.

(The "gauge" measurement originates from muzzleloader guns: a ball of lead fitting into a "n-gauge" barrel would weigh 1/n pounds. Thus a 12-gauge gun is caliber .73, a 20-gauge gun is caliber .62)

The benefit of the smaller shell size is reduced recoil, and less damage to the meat when hunting small game.

20 gauge, magnum
Magnum Shells are standard Buckshot shells fitted with a higher internal powder load, increasing velocity and stopping power. The downside is more damage done to a firearm due to the higher overall pressure, requiring more regular maintenance.

20 gauge, slug
Slugs contains a large lead projectile promoting better accuracy and kinetic energy over a distance. Slugs enable a shotgun to engage targets at a further distance and are commonly used to shoot large animals where use of rifles are forbidden.

20 gauge, 3/0 buck
A sub-type added with the new add-on Gun Runners' Arsenal, these loads sacrifice quantity for quality, in other words there are fewer projectiles overall but they're heavier and pack a bigger punch.

20 gauge, pulse slug
A sub-type added with the new add-on Gun Runners' Arsenal, these slugs punch through armor more effectively, and the target gets an extra kick from an Electromagnetic Pulse triggered by the impact.
