12 ga. Flechette Shells

 is a type of 12 Gauge ammunition that appeared exclusively in Fallout Tactics.

This ammunition can be devastating against poorly armored humans and creatures.

Behind the scenes
Unlike standard shotgun rounds, which fire a dispersing cloud of round-ball shot, flechette rounds are designed specifically for antipersonnel applications against unarmored or armored targets. Although the primary propellant charge and wadding scheme remain the same, the round-ball shot is replaced with a cluster of small darts, typically forged from carbon steel or a harder metal. Armor-piercing flechettes can be made from tungsten, osmium, or even depleted uranium for large weapons.
