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 consist of a hull loaded with pistol powder and using multiple projectiles. Due to their low cost, wide availability, and relatively large size, breaking down 20 gauge shells can be a decent way of acquiring lead and pistol powder--if you have the primers and cases ready, it is generally cheaper to break down 20 gauge shells and manufacture your own pistol cartridges than to buy them directly.

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 contain a large lead projectile promoting better accuracy and kinetic energy over a distance. Slugs enable a shotgun to engage targets at a further distance.

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.
