In a side-by-side comparison with the .50 BMG (43 g), the 15 gr (1 g) titanium round of any caliber released almost 2.8 times the energy of the .50 BMG (1 g at 10 000 m/s = 50 000 joules), with only a 27% mean loss in momentum. Energy, in most cases, is what is lethal to the target, not momentum.
Subsonic loads for 9×19mm Parabellum commonly use 9.5 g (147 gr) bullets at velocities of 300 m/s (980 ft/s). For these ammunition loads, balancing bullet weight and velocity are required to ensure that the ammunition will still reliably cycle semi-automatic firearms. Subsonic ammunition with normal bullet weights often fails to function ...
Bullets used in many cartridges are fired at muzzle velocities faster than the speed of sound [10] [11] —about 343 metres per second (1,130 ft/s) in dry air at 20 °C (68 °F)—and thus can travel substantial distances to their targets before any nearby observers hear the sound of the shots.
A penetration depth of 12.5 to 14 inches (320 to 360 mm) may seem excessive, but a bullet sheds velocity—and crushes a narrower hole—as it penetrates deeper, so the bullet might be crushing a very small amount of tissue (simulating an "ice pick" injury) during its last two or three inches of travel, giving only between 9.5 to 12 inches (240 ...

A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as above Mach 5, or above 5 times the speed of sound. [1] Below Mach 1, weapons would be characterized as subsonic, and above Mach 1, as supersonic. Typical Low Earth Orbit atmospheric re-entry speed is Mach 25. [2]
Plus, new research is finding that low rep ranges (1 to 5 reps), typically associated with training power, can still help you build muscle. Win-win, if you ask us. Win-win, if you ask us. Race ...
The .375 Viking bullet had an overall length of 70 mm (2.756 in) and derived its anticipated low drag from a radical LD Haack or Sears-Haack profile in the bullet's nose area. Rifles chambered for this wildcat cartridge, with a cartridge overall length of 119 mm (4.685 in), were to have been equipped with custom made 762 mm (30 in) long 203 mm ...
