Another cool “brttttttttt video.”
Filmed throughout acceptance trials for a new lot of ammunition, this impressive clip shows a GAU-8/A Avenger Gatling Gun firing from a test stand.
What makes this video interesting is the fact that although the muzzle was placed 40 feet from the camera you can clearly hear the noise of the A-10’s 30mm rotary cannon firing 170 rounds during this 2,3 sec. long burst.
The Avenger cannon is the Hog primary weapon and is able to fire 3,900 bullets per minute: placed in the A-10 fuselage, each of its seven barrels has an internal riffling groove which passes through the whole length of the barrel so that a spin on each round can be induced.
