The Definition of Cylindro Conoidal Bullet
Cylindro Conoidal Bullet
A hollow base bullet, shaped so that, when fired, the bullet will expand and seal the bore.
It was invented by Captain John Norton of the British 34th Regiment in 1832, after he examined the blow pipe arrows used
by the natives in India and found that their base was formed of elastic locus pith, which by its expansion against the
inner surface of the blow pipe prevented the escape of air past it.

A shooting sport that combines both skiing and rifle shooting. It is the only shooting activity in the Winter Olympics.
There is also a summer biathlon which involves running and shooting but it is not yet an Olympic event.
A part in a firearm that serves to remove brass cases of fired ammunition after the ammunition has been fired.
When the gun's action cycles, the extractor lifts or removes the spent brass casing from the firing chamber.
Single shot pistols, of a design originating in England, in vogue circa 1770 - 1850, built necessarily in pairs, either of flintlock or percussion ignition,
usually finely made and cased together with loading accessories. Dueling pistols tended to be lighter and sleeker than their contemporary service pistols.
They tended to have smoothbore (or sometimes secret, scratch-rifling), octagon (or octagon-to-round) barrels around nine or ten inches long of some form of damascus steel,
bores just over a half-inch, ramrods, rudimentary sights front and rear, single-set triggers, roller-bearing frizzens and curved grips integral with full or half-stocks.
They were usually of high quality construction, sometimes with silver furniture, but normally of relatively plain decoration.
An early form of muzzle-loading revolver wherein, instead of the current practice of having one barrel mated to a multi-chambered rotating cylinder,
multiple joined barrels revolve together around a central axis.
A shotgun, generally stocked to shoot where it is pointed and of relatively light weight because one often carries it a great distance for upland birds,
the consequent recoil not being an important factor because one actually shoots it very little.
A muzzle flash is the visible light of a muzzle blast, which expels high temperature, high pressure gases from the muzzle of a firearm.
The blast and flash are caused by the combustion products of the gunpowder, and any remaining unburned powder,
mixing with the ambient air. The size and shape of the muzzle flash is dependent on the type of ammunition being
used and the individual characteristics of firearm and any devices attached to the muzzle (such as a muzzle brake or flash suppressor)
A type of reflector (reflex) sight for firearms that gives the uses a red light-emitting diode as a reticle to create an aimpoint.
A shotgun with two barrels, usually of the same gauge or bore.
The two types of double-barreled shotguns are over/under (abbreviated as O/U or OU),
in which the two barrels are stacked on top of each other, and side-by-side (abbreviated as SxS),
in which the two barrels sit beside each other. See photo at right for example of side-by-side double-barreled shotgun.
For double-barreled guns that use one shotgun barrel and one rifle barrel, see combination gun.
A semi-automatic firearm whose breechblock and barrel are not mechanically locked together when fired.
In such case the breechblock immediately begins to separate from the barrel upon firing.
Blowback is used in comparatively low powered weapons, in which inertia of the breechblock, and cartridge wall adhesion against the chamber,
are sufficient enough to retard opening until breech gas pressures have fallen to a safe level.
Abbreviation for Double Action Only. Is a type of firearm in which the firing mechanism cannot be cocked in a single-action stage. Firing always occurs as a double-action sequence where pulling the trigger both cocks and then fires the gun.
Anything that can be used in an offensive attack or in defense of an offensive attack. Guns are not necessarily weapons.
A gun can be used as a weapon, but so can a pencil, fist, car, a wad of paper or any other object used to attack or retaliate against an offensive attack. Even words can be used as a weapon.
Guns and other objects should be always called what they are; gun, rifle, pistol, pencil, knife, tomato or whatever they are. They should never be referred to as a weapon, EVER.
Some examples of the proper usage for the word "weapon" would be:
"One weapon used in the attack against the left flank was dirt clods".
"The marshmallow gun was the weapon of choice used in the accounting vs marketing skirmishes."
"The liberal leftists use words and restrictive controlling laws as weapons against the freedom of the people."
The charge used to ignite the propelling charge.

The premier bolt action, whose design by Paul Mauser coalesced in 1898,
and from which were derived the Springfield 1903, the Winchester Model 70 and many others.
A quick shot taken without deliberate aim.
