The remaining element of the round is the tungsten carbide penetrator. This has a large amount of kinetic energy and will penetrate the armor as a solid-cored armor-piercing shot would. This takes the incendiary material and about 20 steel fragments (created by the explosives), delivering them in a 25–30 degree cone through the armor ...
Armour-piercing high-explosive (APHE) shells are armour-piercing shells containing an explosive filling, which were initially termed "shell", distinguishing them from non-explosive "shot". This was largely a matter of British usage, relating to the 1877 invention of the first of the type, the Palliser shell with 1.5% high explosive (HE).
An example would be an improved cylinder choke will perform like a modified choke when shooting steel or tungsten shells. For such hunters, wishing to continue to use older shotguns with chokes not rated for use with steel shot, the use of bismuth shotshells in the place of lead shotshells is common.
However, it was found that steel shot tended to shatter on impact at velocities greater than 823 m/s (2700 feet/second). [4] To counter this, a cap of softer metal was attached to the tip of an AP (solid) round. The cap transferred energy from the tip of the shell to the sides of the projectile, thereby helping to reduce shattering.
The principle of the kinetic energy penetrator is that it uses its kinetic energy, which is a function of its mass and velocity, to force its way through armor. If the armor is defeated, the heat and spalling (particle spray) generated by the penetrator going through the armor, and the pressure wave that develops, ideally destroys the target.
Within recent years, several companies have created non-toxic shot out of bismuth, tungsten, or other elements or alloys with a density similar to or greater than lead, and with a shot softness that results in ballistic properties that are comparable to lead. These shells provide more consistent patterns and greater range than steel shot.
Asbestos, a known human carcinogen, can be injurious to consumers if found in talc-containing cosmetic products as there is no established "safe level" threshold for exposure to the substance. If ...
A taller brick shot tower painted with a large "P" became a local landmark. [3] Remington Arms purchased the Peters Cartridge Company in 1934. [5] Facilities were expanded during World War II to include the federally owned Kings Mills Ordnance Plant manufacturing military ammunition on an adjacent hill south of the Peters factory complex.
