摘要： Shot shells with enhanced performance due to inclusion of an absorber between the shot wad and the shot payload. The absorber reduces the pressure within a shot gun's chamber during firing of the shell, such as by absorbing energy generated during the firing process, and may thereafter return some of the energy to the pellets as the absorber and pellets are propelled along the firearm's barrel. Accordingly, the absorber enables a shot shell to generate shot payload velocities that are greater than would be achieved without the absorber, typically at a lower internal chamber pressure. In some embodiments, the absorber has (1) a Young's Modulus of less than 2,000 psi (137.9 bar), (2) a compressive strength of at least 100 psi (6.9 bar) and/or less than 10,000 psi (689.5 bar), and/or (3) a tensile strength of at least 145 psi (10 bar) and/or less than 10,000 psi (689.5 bar).

摘要： Frangible firearm projectiles, firearm cartridges containing the same, and methods for forming the same. The firearm projectiles are formed from a compacted mixture of metal powders that includes zinc and iron powders and which may include an anti-sparking agent. The compacted mixture is heat treated for a time sufficient to form a plurality of discrete alloy domains within the compacted mixture. The frangible firearm projectile may be formed by a mechanism that includes vapor-phase diffusion bonding and oxidation of the metal powders and that does not include forming a liquid phase of any of the metal powders or utilizing a polymeric binder. A majority component of the frangible firearm projectile may be iron. One or more of zinc, bismuth, tin, copper, nickel, tungsten, boron, and/or alloys thereof may form a minority component of the frangible firearm projectile. The anti-sparking agent may include a borate, such as boric acid.

摘要： Frangible firearm projectiles, firearm cartridges, and methods for forming the same. The projectiles are formed from metal powder and include an anti-sparking agent. One or more of iron, zinc, bismuth, tin, copper, nickel, tungsten, boron, and/or alloys thereof may form the metal powder. The projectiles may be formed from a compacted mixture of two or more different metal powders. The anti-sparking agent may include a borate, such as boric acid, zinc chloride, and/or petrolatum. The anti-sparking agent may be dispersed within, and/or applied as a coating on, the exterior of the projectile. The compacted mixture may be heat treated for a time sufficient to form a plurality of discrete alloy domains within the compacted mixture. Such domains may be formed by a mechanism that includes vapor-phase diffusion bonding and oxidation of the metal powders and that does form a liquid phase of the metal powder or utilize a polymeric binder.

摘要翻译：由于在射击篮和射击有效载荷之间包含吸收器，炮弹具有增强的性能。吸收器在烧制壳体期间降低了枪枪室内的压力，例如通过吸收在焙烧过程中产生的能量，然后随着吸收器和丸粒沿着枪支的枪管被推进，这些能量可以将一些能量返回到丸粒中。因此，吸收器使得射击壳体能够产生大于在没有吸收器的情况下通常在较低内部室压力下实现的射击有效载荷速度。在一些实施例中，吸收器具有（1）小于2,000psi（137.9巴）的杨氏模量，（2）至少100psi（6.9巴）和/或小于10,000psi（689.5巴）的压缩强度，和/或（3）至少145psi（10bar）和/或小于10,000psi（689.5巴）的拉伸强度。
