The Army's new weapon will look like a light machine gun, but will put M1 Abrams Main Battle Tank-style blasting power literally at the fingertips of U.S. soldiers… link |

LOL, nowhere near the "blasting power" of a tank. Awesomely crap technical journalism (almost as daft as the infamous 5" gun story from a few years back) |

It's on the Internet. It has to be true. |

Powerful as a Panzer Mk. I? Hey, it's a tank! |

Apparently it involves the same "pressure" as a tank gun. |

It works as advertised. The ballistic pressure when the round leaves the barrel is nearly exact as what the 120mm SB fires. Nowhere in the article does it clam to penetrate like a 120mm gun! The lighter weight for gun and ammo, rate of fire and longer barrel wear should be very welcomed by our warfighters. |

Sure, except it says that the round is designed to operate at 60,000 to 80,000 PSI, then quite INCORRECTLY asserts that modern assault rifle cartridges operate at 45,000 PSI. This is patently false. The 5.56x45mm NATO cartridge (and associated weapon chamber) is already designed for a 62,300 PSI loading. The last major military rifle cartridge I am aware of which operated as low as 45,000 PSI was the .303 British, which was limited to very low pressure because it was initially designed as a BLACK POWDER cartridge and couldn't make full use of modern smokeless powders in the 1940s. Even the obsolete-but-still-in-widespread-use Russian 7.62x54mm rimmed round was designed for smokeless powder with a 55,000 PSI operating limit. |
