The .600 Overkill is a hunting cartridge designed to fit the CZ-550 action, by American Hunting Rifles.
The .600 Overkill was designed by Robert Garnick of Las Vegas, Nevada in 2000. The case is a custom, with a belt, .683 in (17.35 mm), added for headspacing and the rim to fit that of the .505 Gibbs .640 in-(16.26 mm) size, bolt face.
This cartridge was intended to fire the largest bullet able to fit in the CZ-550, [2] and was designed specifically for the purpose of killing an elephant. The CZ-550 can fit two cartridges, with slight alterations. The .600 Overkill fires a 900-grain (58 g) bullet at more than 2,400 ft/s (730 m/s),
The .357 Smith & Wesson Magnum, .357 S&W Magnum, .357 Magnum, or 9×33mmR is a smokeless powder cartridge with a 0.357 in (9.07 mm) bullet diameter. It was created by Elmer Keith, Phillip B. Sharpe, and Douglas B. Wesson of firearm manufacturers Smith & Wesson and Winchester. The .357 Magnum cartridge is notable for its highly effective terminal ballistics.
A rim-fire is a type of metallic cartridge used in firearms where the primer is located within a hollow circumferential rim protruding from the base of its casing. When fired, the gun's firing pin will strike and crush the rim against the edge of the barrel breech, sparking the primer compound within the rim, and in turn ignite the propellant within the case. Invented in 1845 by Louis-Nicolas Flobert, the first rimfire metallic cartridge was the .22 BB Cap cartridge, which consisted of a percussion cap with a bullet attached to the top. While many other different cartridge priming methods have been tried since the early 19th century, such as teat-fire and pinfire, only small caliber rimfire cartridges have survived to the present day with regular use. The .22 Long Rifle rimfire cartridge, introduced in 1887, is by far the most common ammunition found in the world today in terms of units manufactured and sold.
The .30-06 Springfield cartridge, 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. In the cartridge's name, ".30" refers to the nominal caliber of the bullet in inches; "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03 Springfield, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. The cartridge remains a very popular sporting round, with ammunition produced by all major manufacturers.
The .460 Weatherby Magnum is a belted, bottlenecked rifle cartridge, developed by Roy Weatherby in 1957. The cartridge is based on the .378 Weatherby Magnum necked up to accept the .458-inch (11.6 mm) bullet. The original .378 Weatherby Magnum parent case was inspired by the .416 Rigby. The .460 Weatherby Magnum was designed as an African dangerous game rifle cartridge for the hunting of heavy, thick skinned dangerous game.
The 9.3×62mm is a rimless, bottlenecked rifle cartridge designed in 1905 by German gunmaker Otto Bock. It is suitable for hunting medium to large game animals in Africa, Asia, Europe, and North America. At a typical velocity of 720 m/s (2362 ft/s), its 286 gr standard load balances recoil and power for effective use at 250m to 300m. The C.I.P. Maximum Average Pressure (MAP) for the 9.3×62mm is 390.00 MPa (56,565 psi).
The .45-70 (11.6x53mmR), also known as the .45-70 Government, .45-70 Springfield, and .45-21⁄10" Sharps, is a .45 caliber rifle cartridge originally holding 70 grains of black powder that was developed at the U.S. Army's Springfield Armory for use in the Springfield Model 1873. It was a replacement for the stop-gap .50-70 Government cartridge, which had been adopted in 1866, one year after the end of the American Civil War, and is known by collectors as the "Trapdoor Springfield".
The .458 Winchester Magnum is a belted, straight-taper cased, Big Five game rifle cartridge. It was introduced commercially in 1956 by Winchester and first chambered in the Winchester Model 70 African rifle. It was designed to compete against the .450 Nitro Express and the .470 Nitro Express cartridges used in big bore British double rifles. The .458 Winchester Magnum remains one of the most popular large game cartridges, and most major ammunition manufacturers offer a selection of .458 ammunition.
The 7.92×57mm Mauser is a rimless bottlenecked rifle cartridge. The 7.92×57mm Mauser cartridge was adopted by the German Empire in 1903–1905, and was the German service cartridge in both World Wars. In its prime, the 7.92×57mm Mauser cartridge was one of the world's most popular military cartridges. In the 21st century it is still a popular sport and hunting cartridge that is factory-produced in Europe and the United States.
The .700 Nitro Express (17.8×89mmR), also known as .700 H&H, is a big-game rifle cartridge. The cartridge is typically charged with around 250 grains of powder, in addition to a two-grain igniter charge. The cartridge was introduced in 1988 by the boutique gunmakers Holland & Holland (H&H) of London. It was developed by Jim Bell and William Feldstein and built by H&H. Feldstein had tried unsuccessfully to get H&H to build a .600 Nitro Express for him, but they had already ceased production. However, when Bell and Feldstein produced an entirely new .700 Nitro Express cartridge, they were able to attract the interest of H&H, which was looking for a new big-bore cartridge. After production began, the backlog of orders was so great that it continued to 2007 and H&H restarted the production of .600 Nitro Express guns.
The .577 Nitro Express is a large-bore centerfire rifle cartridge designed for the purpose of hunting large game such as elephant. This cartridge is used almost exclusively in single-shot and double express rifles for hunting in the Tropics or hot climates in general and is a cartridge associated with the golden age of African safaris and Indian shikars.
The .300 Winchester Magnum is a belted, bottlenecked magnum rifle cartridge that was introduced by the Winchester Repeating Arms Company in 1963. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a .30 caliber (7.62 mm) bullet.
The 8×68mm S rebated rim bottlenecked centerfire rifle cartridge was developed in the 1930s by August Schüler of the August Schüler Waffenfabrik, Suhl, Germany as a magnum hunting cartridge that would just fit and function in standard-sized Mauser 98 bolt-action rifles. The bore has the same lands and grooves diameters as the German 7.92×57mm Mauser service cartridge. This is one of the early examples where a completely new rifle cartridge was developed by a gunsmith to fit a specific popular and widespread type of rifle.
The .505 Gibbs cartridge was designed by George Gibbs in 1911. The cartridge was originally known as the .505 Rimless Nitro Express. The C.I.P. refers to the cartridge as the 505 Mag. Gibbs in their publications. It is a .50 caliber (12.8 mm) rimless bottlenecked cartridge intended for magazine-fed rifles.
The 9.3×64mm Brenneke is a rimless bottlenecked centerfire rifle cartridge designed in 1927 by German gunmaker Wilhelm Brenneke. It is suitable for hunting medium to large game animals in Africa, Asia, Europe, and North America.
The .458 Lott is a .458 caliber rifle cartridge designed for the purpose of hunting large, thick-skinned dangerous game animals in Africa. It is based on the full length .375 H&H Magnum case blown out and shortened to 2.800 inches (71.1 mm).
The CZ-550 is a bolt-action hunting rifle series manufactured by Česká zbrojovka Uherský Brod. The CZ 550 series is available with a medium or magnum sized action. The CZ 550 rifle is based on the Mauser 98 rifle.
The .450 Rigby is a rifle cartridge designed in 1994 by John Rigby & Co. for the purpose of hunting large, thick-skinned dangerous African game animals. The cartridge is essentially a .416 Rigby necked up to accept a .458 in (11.6 mm) bullet, although with a higher operating pressure and much of the original taper removed. It is intended for use in magazine rifles. The cartridge should not be confused with .450 Nitro Express, introduced by Rigby in 1898, which is a rimmed cartridge of lesser performance intended for use in double and single shot rifles.
The .500 S&W Magnum or 12.7×41mmSR is a .50 caliber semi-rimmed revolver cartridge developed by Cor-Bon in partnership with the Smith & Wesson "X-Gun" engineering team for use in the Smith & Wesson Model 500 X-frame revolver and introduced in February 2003 at the SHOT Show. It was intended to be the most powerful handgun cartridge to date, with the capacity to harvest all North American game species. More powerful handgun cartridges, such as the .500 Bushwhacker, have emerged since, however.
The .500 Whisper or .500 Whisper Short Belted is a subsonic rifle cartridge developed by SSK Industries for use in suppressed rifles. It is capable of firing a .51 caliber bullet weighing 750 gr (49 g) at roughly 1,050 ft/s (320 m/s).
600 is a year.
