Hydra-Shok is a type of expanding bullet made by Federal Cartridge. It was originally patented by bullet designer Tom Burczynski. Hydra-Shok was debuted in 1988 after the FBI requested a bullet with better terminal ballistics than traditional cup and core projectiles.[1] Hydra-Shok bullets feature a unique, patented center-post design and notched jacket with a non-bonded lead core. Together they are meant to provide more reliable expansion and deeper penetration than the other projectiles used at that time. Center post designed bullets like Hydra-Shok have more predictable results and therefore offer some advantage as a projectile. The manufacturer says that the scored jacket and center post design provide a "programmed" expansion. There has been much debate regarding the bullets unreliable expansion when fired through clothing or medias other than ballistic gelatin.[citation needed] In ballistic gelatin, the bullet typically displays very rapid expansion resulting in a larger but more shallow wound channel than would be typical from most other bullet configurations in the same caliber and of similar weight.[citation needed]

The Hydra-Shok bullet is available in various calibers; 9 mm, 10 mm, .32 ACP, .380 ACP, .38 S&W Special, .357 Magnum, .40 S&W, .45 ACP, .45 GAP, and .44 Magnum. It can also be found in 12ga. shotgun slugs.[2]

The Hydra-Shok cartridge is a JHP(Jacketed Hollow Point) round. Another bullet, referred to as FMJ (Full Metal Jacket) has a smooth, rounded tip designed for accuracy and penetration. A hollow point round, however, has a hollow tip that causes it to expand upon impact.
