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.

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.
A gun is a normally tubular weapon or other device designed to discharge projectiles or other material. [20] The projectile may be solid, liquid, gas, or energy and may be free, as with bullets and artillery shells, or captive as with Taser probes and whaling harpoons .

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 ...
