Breakdown
Breaking down a standard 20 Gauge Round yields:

Weapons using this ammunition

 * Caravan Shotgun
 * Sturdy Caravan Shotgun
 * Lever-Action Shotgun
 * Single Shotgun

20 Gauge, Magnum
Magnum shells are standard buckshot shells fitted with a higher internal powder load, increasing velocity and stopping power. The downside is that they cause more damage to the firearm used 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 Round (Junk)
A round made from refuge materials, their shoddy quality increases wear on the weapon by 1.5x and deals 25% less damage to targets.

20 Gauge, 3/0 Buck
A sub-type added with the 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, 3/0 Buck Mag. (Hand Loader)
A sub-type added with the add-on Gun Runners' Arsenal, these magnum shells use the larger 3/0 shot size, but with a greater powder load resulting in higher velocity. The Hand Loader perk is required to craft it.

20 Gauge, Pulse Slug
A sub-type added with the add-on Gun Runners' Arsenal, these slugs cause more damage to power armor and robots, and the target gets an extra kick from an electromagnetic pulse triggered by the impact.
