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]
However, a few companies produce pistol ammunition with plastic-tipped hollow points where the plastic is molded into a more rounded tip. These designs are not created to increase the streamlining of the bullet but rather to improve ammunition feeding in semi-automatic pistols that are prone to jams with standard hollow point ammunition.
The original round was a hand-made hollow-point bullet filled with No. 12 birdshot (0.05 in (1.3 mm)) with a flat polymer cap.

Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
