A snout is the protruding portion of an animal's face, consisting of its nose, mouth, and jaw. In many animals, the structure is called a muzzle , [ 1 ] rostrum , beak or proboscis . The wet furless surface around the nostrils of the nose of many mammals is called the rhinarium (colloquially this is the "cold wet snout" of some mammals).
Muzzle velocity: The speed at which a projectile leaves the muzzle of the gun. Muzzle velocities range from approximately 800 ft/s (240 m/s) for some pistols and older cartridges to more than 4,000 ft/s (1,200 m/s) in modern cartridges such as the .220 Swift and .204 Ruger .
Muzzle (anatomy) or snout, the projecting parts of the face (including the nose and mouth) of an animal Muzzle (mouth guard), a device that covers an animal's snout; Muzzle (firearms), the mouth of a firearm; Muzzle (band), a band based in Seattle, Washington, U.S. "Muzzle" (song), a song by the Smashing Pumpkins from Mellon Collie and the ...
Star: a white marking between or above the eyes. If a stripe or blaze is present, a star must be significantly wider than the vertical marking to be designated separately. Snip: a white marking on the muzzle, between the nostrils. Additional terms used to describe facial markings include the following:
The original .357 Magnum load was a 158 gr (10.2 g) bullet with an advertised muzzle velocity of 1,525 ft/s (465 m/s) and muzzle energy of 816 ft⋅lbf (1,106 J). (Muzzle velocity was taken using a large frame revolver with a fairly long barrel of 8.75 in (222 mm)) Most of today's SAAMI conform loads are fairly mild when compared to the ...
"Windage" as applied to British muzzle-loading ordnance referred to the difference between a gun's bore and the projectile's diameter, typically 0.1–0.2 inches (2.5–5.1 mm). This gap was necessary to allow the projectile to be rammed down the length of the barrel on loading.
The external ballistics uses so-called initial velocity Vo, which is not the same as the real muzzle velocity. The initial velocity Vo is calculated via an extrapolation of the decaying part of velocity curve to the position of the muzzle (to). The difference between these two velocities is visible in the chart. [7]
Adding this to barrel jump results in shot jump. In this case, it is the difference between the initial pointing direction of the muzzle and the final trajectory of the center of gravity of the shot as it leaves the barrel. After the shot leaves the muzzle, there will be aerodynamic effects which modify the trajectory.
