An example (open and closed) of a typical gun safe. A gun safe is a safe designed for storing one or more firearms and/or ammunitions.Gun safes are primarily used to prevent access by unauthorized or unqualified persons (such as children), for burglary protection and, in more capable safes, to protect the contents from damage by flood, fire or other natural disasters.
By creating a pressure differential in the barrel after the shell leaves, the bore evacuator causes most of the propellant gases and combustion residues to exit via the muzzle. Thus, when the breech opens for reloading, those gases and residues do not escape into the crew compartment and pose a hazard to the gun crew. [1]
Animal hide and sinew may also have been used to repair damaged firearms or build a new weapon using multiple parts. Historic firearms are identified by barrel style, how they are loaded, and by lock, the firing mechanism. Firearms can first be classified by the barrel style which is described as either a smoothbore or rifle.
A quantity of olive oil and a round shot were left inside in the barrel; With the gun laid horizontally the shot would roll up and down the barrel as the ship caught each wave, effectively lubricating the gun simply through the motion of the ship. [3] Later, the invention of revolving gun turrets meant that all guns were constantly exposed to ...
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.

An "ageing barrel" is used to age wine; distilled spirits such as whiskey, brandy, or rum; beer; tabasco sauce; or (in smaller sizes) traditional balsamic vinegar. When a wine or spirit ages in a barrel, small amounts of oxygen are introduced as the barrel lets some air in (compare to microoxygenation where oxygen is
Burning powder gases melt part of the bore each time a gun is fired. This melted metal is oxidized or blown out of the muzzle until the barrel is eroded to the extent shell dispersion becomes unacceptable. After firing several hundred shells, a gun may be reconditioned by boring out the interior and inserting a new liner as the interior cylinder.
The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm tactics: while a single hit from a frigate's broadside would destroy a gunboat, a frigate facing a large squadron of gunboats could suffer serious damage before it could manage to sink them all.
