Currently A-square is the only other factory ammunition producer of the .340 Weatherby Magnum, which has led to limited popularity of the caliber. In field tests the .340 clearly outperforms the 300 Ultra mag, .338 Win mag. and even rivals the larger .375 H&H, providing a much flatter shooting and harder hitting performance.
If the bullet passes through the target, the energy represented by the square of the velocity of the departing bullet has no effect on the target. Soft point bullets may not expand if they strike a target at low velocity, or if the target does not slow the bullet enough to deform the exposed point or rupture the surrounding jacket. [2]
Traditionally, these bullets are intended for use in rifles and single-shot handguns, as pistols are not normally used at the great distances where the streamlined ballistic tip is advantageous. However, a few companies produce pistol ammunition with plastic-tipped hollow points where the plastic is molded into a more rounded tip.
Handgun bullets made entirely of lead have less penetration ability than jacketed bullets at similar velocity. In the 1930s, Western Cartridge Company introduced .38 Special ammunition capable of firing a 158-grain (10.2 g) copper-tipped lead-alloy bullet at 1,125 feet (343 m) per second to penetrate sheet-metal automobile doors.

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 ...
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. [1]The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors.
Box full of 40×53 mm high-velocity grenades A 40×46 mm low-velocity training round being fired from an M203 grenade launcher. This is a general collection of the world's many types of ammunition for grenade launchers in 40 mm (1.57 in) caliber. Several countries have developed or adopted grenade launchers in 40 mm caliber.

The Steyr-Mannlicher ACR rifle was a prototype flechette-firing assault rifle built for the US Army's Advanced Combat Rifle program of 1989–90. [citation needed] A variation of the flechette addressing its difficulties is the SCMITR, developed as part of the Close Assault Weapon System, or CAWS, project. Selective-fire shotguns were used to ...
