This jacket is formed by pressing a pre-cut sheet of metal over a mandrel that shapes the bullet, a process that ensures consistent weight and diameter, which is vital for ballistic accuracy. This results in a narrow, high-velocity wound channel that transfers kinetic energy primarily through hydraulic shock rather than permanent cavity expansion.

Performance in Ballistics and Terminal Ballistics When a bullet full metal jacket strikes a target, its behavior is largely predictable due to its rigid structure. Reliability: The robust construction resists deformation in the magazine and during the feeding cycle, ensuring smooth operation in semi-automatic firearms.
Barrel longevity: The jacket protects the bullet from leading, which can accumulate in the barrel and affect accuracy, thus extending the functional life of the rifling. Understanding the engineering and application of full metal jacket projectiles is essential for anyone seeking precision, reliability, and predictable behavior from their ammunition.

The exterior shell, usually copper or a copper alloy, serves two critical purposes: it protects the lead core from deformation during the high-pressure stress of firing and during handling, and it reduces barrel fouling by minimizing direct contact between the lead and the rifling. This characteristic makes them unsuitable for self-defense scenarios where maximum stopping power and minimal collateral risk are priorities.
