Before the barrel can release the bullet in a consistent manner, it must grip the bullet in a consistent manner. The part of the barrel between where the bullet exits the cartridge, and engages the rifling, is called the "throat", and the length of the throat is the freebore. In some firearms, the freebore is zero as the act of chambering the ...
Binder originally planned to employ a camera sighted down the barrel of a .38-calibre gun, but this caused some problems. Unable to fit the lens of a standard camera far enough down the barrel to bring the entire gun barrel into focus, his assistant Trevor Bond created a pinhole camera to solve the problem, and the barrel became clear.

All of the Eon Bond films feature the unique gun barrel sequence, created by graphic artist Maurice Binder, which has been called by British media historian James Chapman "the trademark motif of the series". [5] As Bond walks across the screen, he is viewed by the audience through the barrel of a gun trained on him by an unknown assailant.
The gun barrel sequence as it appears in Dr.No (1962). The gun barrel sequence is a signature device featured in nearly every James Bond film. [1] Shot from the point of view of a presumed assassin, it features James Bond walking, turning, and then shooting directly at the camera, causing blood to run down the screen.
Gun dynamics describes the physical causes of barrel and shot vibration, and the effect they may have on accuracy and consistency. It is employed to predict firearm performance, such as recoil , using theoretical methods and mathematical modelling techniques.
Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially weapon munitions such as bullets, unguided bombs, rockets and the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.
Pickel did, however, find that the weapon focus effect was mitigated when participants were primed and the perpetrators were categorized as dangerous and aggressive. A different effect of weapon focus can be used in a way to reduce change blindness. A study in 2017 aimed to find a way to reduce change blindness by making use of weapon focus.
A female worker boring out the barrel of a Lee-Enfield rifle during WWI. Gun barrels are usually made of some type of metal or metal alloy.However, during the late Tang dynasty, Chinese inventors discovered gunpowder, and used bamboo, which has a strong, naturally tubular stalk and is cheaper to obtain and process, as the first barrels in gunpowder projectile weapons such as fire lances.
