Hydra-Shok

Hydra-Shok is a type of hollow-point projectile made by Federal Premium Ammunition. It was originally patented by ammunition designer Tom Burczynski. Hydra-Shok was released in 1988 after the FBI requested a bullet with better terminal ballistics than traditional cup and core projectiles.[1]

Design

Hydra-Shok ammunition features a unique, patented center-post design and notched jacket with a non-bonded lead core. Together these design elements are meant to provide more reliable expansion and deeper penetration than other hollow-point ammunition. Center post designed bullets like Hydra-Shok have more predictable results and therefore offer some advantage as a projectile.[2]

The manufacturer says that the scored jacket and center post design provide a "programmed" expansion. There has been much debate regarding the bullet's unreliable expansion when fired through clothing or media other than ballistic gelatin, in which 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.[2]

Calibers

Hydra-Shok ammunition is available in various caliber such as 9 mm, 10 mm, .32 ACP, .380 ACP, .38 S&W Special, 327 Federal Magnum, .357 Magnum, .40 S&W, .45 ACP, .45 GAP, and .44 Magnum. 12-gauge shotgun slugs also incorporate Hydra-Shok technology.[3]
