The propulsion system uses an obturating case base with a semi-combustible cartridge wall. It has a total weight of 41.1 lb (18.6 kg) and a 627 mm (24.7 in) DU penetrator with a 27 mm (1.1 in) rod diameter, [2] which reaches a muzzle velocity of 1,670 meters per second (5,500 ft/s) using 8.1 kg (18 lb) of JA-2 propellant. Its maximum effective ...
The muzzle clamp is a method of killing used by big predators, usually cats such as Panthera leo, the lion, Panthera pardus, the leopard, and Panthera uncia, the snow leopard. It requires the subduing of prey , usually completely on the ground and pinned by the predator, and the engulfing of the muzzle of the prey entirely in the mouth of the ...
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
The Taylor KO factor multiplies bullet mass (measured in grains) by muzzle velocity (measured in feet per second) by bullet diameter (measured in inches) and then divides the product by 7,000, converting the value from grains to pounds and giving a numerical value from 0 to ~150 for normal hunting cartridges.
A muzzle-loading rifle is a muzzle-loaded small arm that has a rifled barrel rather than a smoothbore, and is loaded from the muzzle of the barrel rather than the breech.. Historically they were developed when rifled barrels were introduced by the 1740ies, which offered higher accuracy than the earlier smooth
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.
Probably the most popular weight for the 300 Win Mag is the 180 grain bullet, with high ballistic coefficient and capable of taking down light skinned big game of any weight. The 180 and 185 grain bullets are also considered the most versatile, with a muzzle velocity of 2950 fps from average factory loads. [12] [13]
Illustration of forces in muzzle rise. Projectile and propellant gases act on barrel along barrel centerline A. Forces are resisted by shooter contact with gun at grips and stock B. Height difference between barrel centerline and average point of contact is height C. Forces A and B operating over moment arm / height C create torque or moment D, which rotates the firearm's muzzle up as ...
