9×25mm Dillon
The 9×25mm Dillon is a pistol wildcat cartridge developed for use in USPSA/ IPSC Open guns. The cartridge is made by necking down (reducing the diameter of the "neck" of the case to suit a new caliber) a 10mm Auto case to 9 mm. History Around 1987, Randy Shelley, an employee of Dillon Precision, necked down 10mm Auto brass to 9 mm. His goal was to get as much slow-burning powder in the case as possible in order to drive a 9 mm bullet to the velocity needed to qualify for the then-IPSC major power factor of 175. The short-necked and steep-shouldered cartridge holds twice the powder of a .38 Super Auto case. The 9×25mm Dillon was used by several notable IPSC shooters, such as Rob Leatham and Jack Barnes. Most shooters, looking at the 9×25mm Dillon today, focus on the extreme velocities of which it is capable. A 115-grain bullet at 1,800 fps is more than is needed for competition. There, a 115 only needs to be going a bit over 1,500 ft/s to qualify for major power factor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Percussion Cap
The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. Its invention gave rise to the caplock mechanism or percussion lock system which used percussion caps struck by the hammer to set off the gunpowder charge in rifles and cap and ball firearms. Any firearm using a caplock mechanism is a percussion gun. Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle. Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot. Description The percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is a small amount of a shock-sensitive explosive material such as mercury fulminate (discovered in 1800; it was the only practical detonator used from about the mid-19th century to the early 20th century). ...

Power Factor (pistol)
Power factor (PF) in practical shooting competitions refers to a ranking system used to reward cartridges with more recoil. Power factor is a measure of the momentum of the bullet (scaled product of the bullet's mass and velocity), which to some degree reflects the recoil impulse from the firearm onto the shooter (see section on limitations). Power factor is used in competitions sanctioned by the International Practical Shooting Confederation (IPSC), United States Practical Shooting Association (USPSA), Bianchi Cup, Steel Challenge and International Defensive Pistol Association (IDPA). Calculation The PF is based on the bullet's momentum as it is moving through the air by measuring the ''bullet speed'' using a chronograph and measuring a similar ''bullet mass'' on a weighing scale, thereafter calculating the ''power factor'' by the formula: : = \cdot Units The PF can be represented using different units: *The SI-unit ''newton-second'' (kg⋅m/s, or simply N⋅s), by ...

9×30mm Grom
The 9×30mm ''Grom'' (Гром., Russian for Thunder) is a Russian round developed between 1992 and 1993, designed for the Gepard (submachine gun), it answers the need to defeat 1B2 body armor at a range of 100 meters. Development 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. The case is a cutdown 5.45×39mm (also blankfiring) round, manufactured from phosphate varnished steel. The propellants used are pyroxylin (standard Soviet pistol powder "П-45","П-125" also used for blankfiring 5.45×39mm and 7.62×39mm) or smokeless powder consisting of spherical ellipsoids which measure from 0.45–0.75mm, resulting in powder density of 0.95g/cm3.

40 S&W
The .40 S&W (10.2×22mm) is a Rim (firearms), rimless pistol Cartridge (firearms), cartridge developed jointly by American firearms manufacturers Smith & Wesson and U.S. Repeating Arms Company, Winchester in 1990. The .40 S&W was developed as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9 mm size) semi-automatic handguns. It uses bullets ranging in weight from .''Hornady Handbook of Cartridge Reloading'', Fourth Edition (1991), pp. 593–595 History In the aftermath of the 1986 FBI Miami shootout, in which two FBI special agents were killed and five wounded, the FBI started the process of testing 9×19mm Parabellum and .45 ACP ammunition in preparation to replace its standard-issue revolver with a semi-automatic pistol. The semi-automatic pistol offered two advantages over the revolver: increased ammunition capacity and increased e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
357 SIG
The .357 SIG (designated as the 357 Sig by the SAAMI and 357 SIG by the C.I.P. or 9×22 mm in official metric notation) is a bottlenecked rimless centerfire handgun cartridge developed by the Swiss-German firearms manufacturer SIG Sauer, in cooperation with ammunition manufacturer Federal Premium. The cartridge is used by a number of law enforcement agencies.''The Gun Digest Book of Sig-Sauer: a complete look at Sig-Sauer pistols.'' Massad Ayoob. 2004. pp. 51–53. History The .357 SIG is based on a necked-down .40 Smith & Wesson case, forgoing the large pistol primer utilized by the 10mm Auto in favor of the small pistol primer used in many common self-defense rounds, such as .40 S&W, .38 Special, 9 mm and other similarly-sized cartridges. Excluding specialized wildcat cartridges used in competition shooting — e.g., the 9×25mm Dillon, which necked a 10mm Auto case down to a 9 mm bullet — the .357 SIG was the first modern bottlenecked handgun cartridge to become ...

224 Boz
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, ending up with a digit very close to the original Brahmin cross. While the shape of the character f ...
