Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head ( centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin ( pinfire, now obsolet ...

25 ACP
The .25 ACP ( Automatic Colt Pistol) (6.35×16mmSR) is a semi-rimmed, straight-walled centerfire pistol cartridge introduced by John Browning in 1905 alongside the Fabrique Nationale M1905 pistol. Design The cartridge is of semi-rimmed design meaning that the rim protrudes slightly beyond the diameter of the base of the cartridge so the cartridge can headspace on the rim.*Wilson, R. K. ''Textbook of Automatic Pistols''. Plantersville, SC: Small Arms Technical Publishing Company, 1943. p. 258. . Though the .25 ACP was designed for semi-automatic pistols, various .25 ACP revolvers were produced in the early twentieth century by Belgian, French, and German gunmakers such as Adolph Frank and Decker. In the late twentieth century, Bowen Classic Arms produced a custom Smith & Wesson revolver in .25 ACP.Bowen, Hamilton. ''The Custom Revolver''. Privately printed, 2001. . Performance The use of the .25 ACP allows for a very compact lightweight gun, usually pocket pistols, but th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 NAA
The .25 NAA is a pistol cartridge introduced by the North American Arms company in 2002. It was originally created for use in a smaller and lighter model of their Guardian pistol.

25-45 Sharps
The 25-45 Sharps (6.35×45mm) is a firearms cartridge designed by Michael H Blank, then CEO of the Sharps Rifle Company, LLC, as a general hunting cartridge for most North American game, in particular Deer, Antelope, Hogs, and Coyotes. Unlike 300 AAC Blackout which was targeted specifically at the suppressed rifle market, and adapted to hunting, the 25-45 Sharps was designed primarily as a hunting round. That is not to say the round does not have tactical applications as its ballistics exceed that of the 5.56x45mm NATO cartridge. The cartridge name is derived from its caliber ( bullet) and case length of 45 millimeters (necked-up 5.56×45 mm), as opposed to older hyphenated cartridges that were named for caliber and powder charge. Factory ballistics with the bullet equal those of the original .250-3000 Savage with the same bullet weight.

250-3000 Savage
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of ...

257 Roberts
The .257 Roberts, also known as .257 Bob, is a medium-powered .25 caliber rifle cartridge. It has been described as the best compromise between the low recoil and flat trajectory of smaller calibers such as the 5 mm (.22") and 6 mm (.24"), and the higher energy but harder recoil of larger popular hunting calibers, such as the 7 mm (.28") family and the popular 7.62 mm (.30").The .257 Roberts (.257 Roberts +P) by Chuck Hawks (membership required) Nominal bullet diameter of the .257 Roberts is .257 inches.
