Earlier J. D. Jones had already developed the similar .500 Whisper round, which has a roughly .4 in (10 mm) longer belted bottlenecked case based on the .378 Weatherby Magnum. Despite the large bullet, this round is very quiet when using a suppressor due to the subsonic nature of the cartridge. When used with a very high ballistic coefficient ...
The M79 grenade launcher is a single-shot, shoulder-fired, break-action grenade launcher that fires a 40×46mm grenade, which uses what the US Army calls the High-Low Propulsion System to keep recoil forces low, and first appeared during the Vietnam War.
The A-10 engines were initially susceptible to flameout when subjected to gases generated in the firing of the gun. When the GAU-8 is being fired, the smoke from the gun can make the engines stop, and this did occur during initial flight testing. [4] Gun exhaust is essentially oxygen-free, and is capable of causing flameouts of gas turbines ...
M1 Thumper (also known as ATAC System Demonstrator) was a single M1A1 [256] fitted with a heavily modified unarmored M1A1 turret to trial the experimental XM291 ATAC (sometimes referred to as LW120) smoothbore gun, a more powerful replacement for the M256 capable of firing either single-piece 120 mm or two-piece 140 mm ammunition with only a ...
The .450 Bushmaster is descended from the Thumper concept popularized by the gun writer Jeff Cooper.Cooper was dissatisfied with the small-diameter 5.56×45mm NATO (.223 Remington) of the AR-15, and envisioned a need for a large bore (.44 cal or greater) cartridge in a semi-automatic rifle to provide one-shot kills on big-game animals at 250 yards.
A gun was found wrapped in tinfoil inside a teapot filled with shot glasses at Portland International Airport. 6. An e-cigarette was found inside a Colgate toothpaste tube at Chicago Midway ...
A secretary bought three shares of her company's stock for $60 each in 1935. Grace Groner reinvested her dividends for 75 years, and her stake ballooned to $7.2 million.
If the bullet velocity is capped at 1,000-Feet Per Second / FPS in order to subdue the noise of firing, then the impact can be improved by increasing the weight of the bullet. The 357 Auto can be loaded with bullets in .358-caliber, while still fitting within the AR-15 COAL of 2.260". Bullet weights are currently available between 225gr-310gr
