444 Marlin
The .444 Marlin (10.9×57mmR) is a rifle cartridge designed in 1964 by Marlin Firearms and Remington Arms. It was designed to fill in a gap left by the older .45-70 when that cartridge was not available in any new lever-action rifles; at the time it was the largest lever-action cartridge available. The .444 resembles a lengthened .44 Magnum and provides a significant increase in velocity. It is usually used in the Marlin 444 lever-action rifle. History In the mid-1960s the .45-70 had all but disappeared from the American marketplace. There was no big-bore cartridge available in a lever-action rifle in current production, so Marlin decided to create a new cartridge to fill this empty niche. They created what is essentially an elongated version of the .44 Magnum by making it nearly an inch longer to give it power similar to the .45-70."A Hard-Hitter in Rifle or Gandgun by Dr. George E. Dvorchak, Jr. in The case Marlin created is very similar to a rimmed .303 British trimmed an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
308 Winchester
The .308 Winchester is a smokeless powder rimless bottlenecked rifle cartridge widely used for hunting, target shooting, police, military, and personal protection applications globally. It is similar but not identical to the 7.62×51mm NATO cartridge. History During the 1940s, the .300 Savage became the basis for experiments on behalf of the U.S. military that resulted in the development of the T65 series of experimental cartridges. The original experimental case design by the Frankford Arsenal was designated the T65 and was similar to the .300 Savage case, but with less taper. The experimental cases were made from standard .30-06 Springfield cases which gave a little less capacity than standard .300 Savage cases because the Frankford Arsenal cases had slightly thicker case walls. The later T65 iterations were lengthened compared to the original T65 case and provided a ballistic performance roughly equal to the U.S. military .30-06 Springfield service cartridge.

Handloading
Handloading, or reloading, is the practice of making firearm cartridges by assembling the individual components (case, primer, propellant, and projectile), rather than purchasing mass-assembled, factory-loaded ammunition. The term ''handloading'' is the more general term, and refers generically to the manual assembly of ammunition. ''Reloading'' refers more specifically to handloading using previously fired cases and shells. The terms are often used interchangeably however, as the techniques are largely the same, whether the handloader is using new or recycled components. The differences lie in the initial preparation of cases and shells; new components are generally ready to load, while previously fired components often need additional procedures, such as cleaning, removal of expended primers, or the reshaping and resizing of brass cases. Reasons for handloading Economy, increased performance and accuracy, commercial ammunition shortages, and hobby interests are all ...

405 Winchester
The .405 Winchester (also known as the .405 WCF) is a centerfire rifle cartridge introduced in 1904 for the Winchester 1895 lever-action rifle.Cartridges Of The World, Frank Barnes, Krause Publications It remains to this day one of the most powerful rimmed cartridge designed specifically for lever-action rifles; the only modern lever action cartridges that exceed its performance are the .50 Alaskan, .450 Alaskan, .475 Turnbull, .348 Turnbull and the .450 Marlin. The .405 was highly regarded by U.S. President Theodore Roosevelt during his safari in East Africa.Roosevelt, Theodore. "Trekking Through the Thirst to the Sotik." African Game Trails. New York: Charles Schribner's Sons, 1910. 166-67. Print.

348 Winchester
Year 348 ( CCCXLVIII) was a leap year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Philippus and Salia (or, less frequently, year 1101 ''Ab urbe condita''). The denomination 348 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

450 Marlin
The .450 Marlin is a firearms cartridge designed as a modernized equivalent to the .45-70 cartridge. It was designed by a joint team of Marlin and Hornady engineers headed by Hornady's Mitch Mittelstaedt, and was released in 2000, with cartridges manufactured by Hornady and rifles manufactured by Marlin, mainly the Model 1895M levergun. The Browning BLR is also now available in .450 Marlin chambering, as is the Ruger No. 1. Marlin ceased manufacture of the 1895M rifle in 2009. In October 2022 it was rumored that Ruger Firearms the new owner of Marlin Firearms may be reintroducing the 450 Marlin in their Model 1895 guide gun but this has not been confirmed by Marlin or Ruger. Design While ballistically similar to the .45-70, the .450 Marlin was not developed from the .45-70. Rather, the .450 Marlin was developed from the wildcat .458×2" American, which was based on the .458 Winchester Magnum. This places the .450 Marlin in the .458 Winchester family of cartridges, thoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cor-Bon
Cor-Bon/Glaser LLC is a manufacturer of small arms ammunition. History Founded in Sturgis, South Dakota, Cor-Bon/Glaser Ammunition originated when Peter Pi Sr. started making handgun hunting ammo in 1982 because the commonly available ammunition at that time was performing poorly. Pi noticed that hollow point ammunition would not expand and went about creating a line of ammunition with reliable expansion. In 2017 the Company was sold to TA Perrine and moved to Wooster, OH. In 2021 the company was sold again to an investment group out of Sandusky, OH, CorBon Law Enforcement Training Center On June 23, 2011 the company opened the CorBon Law Enforcement Training Center (CLETC) in Sturgis, South Dakota. The center has several shooting ranges to train law enforcement officers. CLETC closed in 2015 due to a lack of business.

Ballistic Coefficient
In ballistics, the ballistic coefficient (BC, ''C'') of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass. BC can be expressed with the units kilograms per square meter (kg/m2) or pounds per square inch (lb/in2) (where 1 lb/in2 corresponds to ).

Hornady
Hornady Manufacturing Company is an American manufacturer of ammunition cartridges, components and handloading equipments, based in Grand Island, Nebraska. History The company is currently run by Joyce Hornady's son, Steve Hornady, who took over after his father's death in a plane crash on January 15, 1981. The Piper Aztec, with Hornady at the controls flying in heavy fog, crashed into Lake Pontchartrain while on final approach to New Orleans Lakefront Airport. Pacific Tool Company Steve Hornady worked for Pacific Tool Company from 1960 to 1971, from the time the company moved from California to Nebraska until Pacific Tool was bought by Hornady. Pacific's DL-366 was their final progressive press and Hornady's first, and it is still manufactured by Hornady as the 366 Auto.

Copper Units Of Pressure
Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in firearms. These terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively. In recent years, they have been replaced by the adoption of more modern piezoelectric pressure gauges that more accurately measure chamber pressures and generally give significantly higher pressure values. This nomenclature was adopted to avoid confusion and the potentially dangerous interchange of pressure values and standards made by different types of pressure gauges. For example, it makes little sense to describe a maximum pressure as 300 MPa, and in case the pressure has been measured according to the CUP procedure it should be denoted as 300 MPa (CUP). Pressure is a fundamental physical parameter that is expressed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
45-70
The .45-70 rifle cartridge, also known as the .45-70 Government, was developed at the U.S. Army's Springfield Armory for use in the Springfield Model 1873, which is known to collectors as the "Trapdoor Springfield." The new cartridge 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. Nomenclature The new cartridge was completely identified as the ''.45-70-405'', but was also referred to as the ".45 Government" cartridge in commercial catalogs. The nomenclature of the time was based on three properties of the cartridge: * .45: nominal diameter of bullet, measured in decimal inches, i.e., 0.458 inches (11.63 mm); * 70: weight of black powder, measured in grains, i.e., 70 grains (4.56 g); * 405: weight of lead bullet, measured in grains, i.e., 405 grains (26.38 g). The minimum acceptable accuracy of the .45-70 from the 1873 Springfield was approximately at , however, the heavy, slo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
