Projecting or impelling forward; as, a projectile force.

A projectile constructed so as to take the grooves of a rifle by means of a soft copper band firmly attached near its base or, formerly, by means of an envelope of soft metal. In small arms the modern projectile, having a soft core and harder jacket, is subjected to compression throughout the entire cylindrical part.…

The horizontal line which measures the distance to which a projectile is thrown; the range.

Any solid spherical, cylindrical, or conical projectile of lead or iron, to be discharged from a firearm; as, a cannon ball; a rifball; -- often used collectively; as, powder and ball. Spherical balls for the smaller firearms are commonly called bullets.

Pertaining to projection, or to a projectile. Ballistic pendulum, an instrument consisting of a mass of wood or other material suspended as a pendulum, for measuring the force and velocity of projectiles by means of the arc through which their impact impels it.

A metallic tube, as of a gun, from which a projectile is discharged. Knight.

A tube, as of cane or reed, sometimes twelve feet long, through which an arrow or other projectile may be impelled by the force of the breath. It is a weapon much used by certain Indians of America and the West Indies; -- called also blowpipe, and blowtube. See Sumpitan.

r of the bore, as a cannon or other firearm, or of any tube; or the weight or size of the projectile which a firearm will carry; as, an 8 inch gun, a 12-pounder, a 44 caliber. The caliber of empty tubes. Reid. A battery composed of three guns of small caliber. Prescott.

ngated bullet for small arms to contain a lubricant, or around the rotating band of a gun projectile to lessen the resistance offered to the rifling. Also, a groove around the base of a cartridge, where the extractor takes hold. --Can"ne*lured (#), a.

A kind of short cannon, formerly in use, designed to throw a large projectile with small velocity, used for the purpose of breaking or smashing in, rather than piercing, the object aimed at, as the side of a ship.

A collection of small projectiles, inclosed in a case or canister.

An instrument for measuring minute intervals of time; used in determining the velocity of projectiles, the duration of short-lived luminous phenomena, etc.

hrough the shank of an anchor to insure its turning fluke down. Russell. Crossbar shot, a projectile which folds into a sphere for loading, but on leaving the gun expands to a cross with a quarter ball at the end of each arm; -- used in naval actions for cutting the enemy's rigging.

A deviation from the line of fire, peculiar to oblong projectiles.

The art or science of measuring the force or velocity of projectiles by means of electricity.

r potash, in distinction from the volatile alkali ammonia. -- Fixed ammunition (Mil.), a projectile and powder inclosed together in a case ready for loading. -- Fixed battery (Mil.), a battery which contains heavy guns and mortars intended to remain stationary; -- distinguished from movable battery. -- Fixed bodies,…

chemically, produce explosion. -- Concussion fuze, a fuze ignited by the striking of the projectile. -- Electric fuze, a fuze which is ignited by heat or a spark produced by an electric current. -- Friction fuze, a fuze which is ignited by the heat evolved by friction. -- Percussion fuze, a fuze in which the igniti…

ey adhere to cattle, causing intense annoyance. -- Grapple shot (Life-saving Service), a projectile, to which are attached hinged claws to catch in a ship's rigging or to hold in the ground; -- called also anchor shot.
