Underwater Bullet

AR15 News has a neat post up about a new bullet designed by PNW Arms to be fired under water. The design is called Supercavitating, which basically means…

through liquid in such a way that it causes a gas bubble to form around the object allowing it to continue moving through the liquid at a much higher rate of speed than is usually possible because of the lack of friction.

They have a video demonstrating how the .308 round will travel through 13 one-gallon water jugs. Yeah, its a game changer to say the least.
