Armor Piercing

Armor Piercing, or AP, bullets are specifically designed with a single purpose: to penetrate armor. AP bullets usually have a sharp point, and have cores filled with tungsten carbide or hardened steel. In Fallout, AP bullets have the effect of lowering the target's damage resistance, while decreasing the overall damage that weapon does. Due to a mistake in their design, AP bullets are actually vastly inferior to JHP or FMJ variants. Even against targets with high damage resistance, the reduced damage does not make up for the reduced resistance. In addition, AP bullets do nothing to reduce the damage threshold of the target's armor, making the armor piercing aspect less powerful than intended.
