Made by
Fedetal Cartridge Co. (after licensing it from
Tom Burczynski) this premium
JHP ammunition is made for
self defense and
law enforcement. Like all other premium
JHP ammo, it is manufactured to exacting tolerances, generates consistent
velocities and is
weatherproofed.
Its distinction from other JHP ammo is the design of its bullet. Aside from having a hollow point, it also has a tiny post inside the hollow ogive. This supposedly prevents the hollow point from getting plugged with material you might have to shoot through to hit your target, like wood paneling or glass windshields.
A plugged up hollow point will not expand and might over penetrate.
Its effectiveness in that regard is debatable and is most likely a marketing gimmick more than anything else. But because of its excellent expansion the Hydrashok is still a very excellent defensive round should you ever decide to carry a gun.
