Measuring the ballistic performance of armor is based on determining the kinetic energy of a bullet at impact (E k = 1 ⁄ 2 mv 2). Because the energy of a bullet is a key factor in its penetrating capacity, velocity is used as the primary independent variable in ballistic testing.
The .325 WSM is an efficient, flat shooting 8mm magnum rifle cartridge. Bullet weights range from 125 to 250 gr (8.1 to 16.2 g). Performance is on par with the two other magnum cartridges: 8mm Remington Magnum and the German 8×68mmS cartridge with lighter weight bullets. However, these later two cartridges have a distinct edge of being able to ...
.224 Weatherby Magnum maximum C.I.P. cartridge dimensions. All sizes in millimeters (mm) plus Imperial (inches). The .224 Weatherby Magnum (5.56×49mmB) is a sporting cartridge that was developed in the 1940s by Roy Weatherby, and commercial ammunition was produced starting in 1963.
SMc cartridges were developed in an attempt to produce an efficient cartridge combining low recoil, low heat, and high velocity. [4] The 5 mm/35 SMc has produced velocities in excess of 4,800 ft/s (1,500 m/s) shooting a 30-grain (1.9 g) molybdenum disulfide-coated Berger bullet from a 28-inch (71 cm) Pac-Nor barrel, far higher than its commercial counterpart the .204 Ruger.
The .224 Boz cartridge was developed in the late 1990s, designed as a candidate replacement cartridge for adoption as the standardized NATO ("STANAG") Personal defense weapon PDW round, originally solicited to replace the longstanding NATO standard (STANAG) 9×19mm Parabellum.

A regular and an armor piercing variant were designed, the non-armor piercing bullet taken from the 9×19mm Parabellum and the armor piercing bullet was taken from the RG054 cartridge, it has a black painted tip. [1] The case is a stretched 9x19mm case, manufactured from phosphate varnished steel.
The .378 Weatherby Magnum was designed by Roy Weatherby in 1953. [3] [4] Although inspired by the .416 Rigby, it is an original belted magnum design with no parent case. [5]The cartridge features a high powder capacity relative to its bore size, and can hold upwards of 7.13 g (120 gr) of powder.
