Full Metal Jackets
CONCEPT
Full metal jackets, or FMJs, are special metal coatings used on many large-caliber bullets. The entire soft metal bullet (usually lead) is completely, or near-completely encased by the harder metal jacket. They allow the bullet to pierce through thicker surfaces while also increasing firepower.
