Expanding bullets are designed to expand on impact, sometimes as much as twice the diameter. [3] This will slow the bullet down and more of its kinetic energy will be transferred to the target, creating a larger wound channel. For this reason, expanding bullets are often used in hunting because their stopping power increases the chance of a ...
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]
For bullets designed for target shooting, some such as the Sierra "Matchking" incorporate a cavity in the nose, called the meplat. This allows the manufacturer to maintain a greater consistency in tip shape and thus aerodynamic properties among bullets of the same design, at the expense of a slightly decreased ballistic coefficient and higher ...
Critical cartridge specifications include neck size, bullet weight and caliber, maximum pressure, headspace, overall length, case body diameter and taper, shoulder design, rim type, etc. Generally, every characteristic of a specific cartridge type is tightly controlled and few types are interchangeable in any way.
Consistency in bullet production, allied to consistency in the assembly of cartridges (quality control) should give excellent shot-to-shot consistency. [citation needed] The principles of bullet design and flight are classically set out in Franklin Ware Mann's The Bullet's Flight From Powder to Target: Ballistics of Small Arms. [4]
A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired.
The Hydra-Shok bullet features a hollow-point construction which contains a distinctive central post in the base of the hollow. This design makes such bullets easily identifiable in autopsy examinations of gunshot victims. [2] The manufacturer stated that the scored jacket and center post design provide a "programmed" expansion.
Armour-piercing discarding sabot (APDS) was initially the main design of the kinetic energy (KE) penetrator. The logical progression was to make the shot longer and thinner to increase its sectional density, thus concentrating the kinetic energy in a smaller area. However, a long, thin rod is aerodynamically unstable; it tends to tumble in ...
