A spitzer bullet (from German: Spitzgeschoss, "point shot") is a munitions term, primarily regarding fully-powered and intermediate small-arms ammunition, describing bullets featuring an aerodynamically pointed nose shape, called a spire point, sometimes combined with a tapered base, called a boat tail (then a spitzer boat-tail bullet), in order to reduce drag and obtain a lower drag ...
A copper-plated hollow-point loaded in a .44 Magnum, for example, with an original weight of 240 grains (15.55 g) and a diameter of 0.43 inch (11 mm) might mushroom on impact to form a rough circle with a diameter of 0.70 inches (18 mm) and a final weight of 239 grains (15.48 g).
For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
For example, if the vertical projectile position over a certain range reach is within the vertical height of the target area the shooter wants to hit, the point of aim does not necessarily need to be adjusted over that range; the projectile is considered to have a sufficiently flat point-blank range trajectory for that particular target.

The 60mm HVMS autocannon was designed as an infantry support gun mounted on light armored vehicles.. The project commenced in 1977, originally as a joint development between IMI Systems of Israel and OTO Melara of Italy, whereby IMI Systems were expected to develop the gun and ammunition, and OTO Melara the autoloader and a lightweight two-man turret which could be mounted on a variety of ...
Projectile trajectory around a planet, compared to the motion in a uniform gravity field. When a projectile travels a range that is significant compared to the Earth's radius (above ≈100 km), the curvature of the Earth and the non-uniform Earth's gravity have to be considered.
The Lazy Dog (sometimes called a Red Dot Bomb or Yellow Dog Bomb [1]) is a type of small, unguided kinetic projectile used by the U.S. Air Force. It measured about 1.75 inches (44 mm) in length, 0.5 inches (13 mm) in diameter, and weighed about 0.7 ounces (20 g). [1] The weapons were designed to be dropped from an aircraft.
Force (pressure times area) provides an acceleration to the mass of the projectile. Therefore, for a given pressure and barrel diameter, a lighter projectile can be driven from a barrel to a higher muzzle velocity than a heavier projectile. However, a lighter projectile may not fit in the barrel, because it is too thin.
