Elmer Keith
Elmer Merrifield Keith (March 8, 1899 – February 14, 1984) was an American rancher, firearms enthusiast, and author. Keith was instrumental in the development of the first magnum revolver cartridge, the .357 Magnum (1935), as well as the later .44 Magnum (1956) and .41 Magnum (1964) cartridges, credited by Roy G. Jinks as "the father of big bore handgunning." Keith was born in Hardin, Missouri, and overcame serious injuries that he had sustained at age 12 in a fire when he was living in Missoula, Montana. Career During World War II, Keith served as an inspector at the Ogden, Utah, Arsenal. The rifles that he inspected were cartouche stamped with the initials "OGEK" in a rectangular box, on the buttstock. Rifles stamped OGEK without a rectangular box were inspected by Ed Klouser at the same Ogden Arsenal. Magnum revolvers Keith's first major contribution, the .357 Magnum, was the result of handloading the .38 Special cartridge far beyond normally accepted limits, ...

Hardin, Missouri
Hardin is a city in southeast Ray County, Missouri, and part of the Kansas City metropolitan area within the United States. The population was 571 at the 2020 census. History Hardin was laid out in 1868. The community was named for Charles Henry Hardin, 22nd Governor of Missouri. A post office called Hardin has been in operation since 1858. 1993 floods Hardin and its cemetery were affected by the Great Flood of 1993, due to their location near the Missouri River. On July 12, 1993 a levee protecting the town of Hardin broke, flooding the city and the cemetery. The flood waters cut a pond thru the cemetery and swept away 793 burials. Later, under the leadership of Dean Snow, 645 remains were recovered, but most were unidentified. Some were still inside their vaults or caskets (thus helping making identification easier), while others were scattered in the open. Since DNA testing was still in its infancy, bodies and bones had to be identified by the rate of decay, sex, age range, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sturm, Ruger
Sturm, Ruger & Company, Inc., better known by the shortened name Ruger, is an American firearm manufacturing company based in Southport, Connecticut, with production facilities also in Newport, New Hampshire; Mayodan, North Carolina; and Prescott, Arizona. The company was founded in 1949 by Alexander McCormick Sturm and William B. Ruger and has been publicly traded since 1969.

Soft Point Bullet
A soft-point bullet (SP), also known as a soft-nosed bullet, is a jacketed expanding bullet with a soft metal core enclosed by a stronger metal jacket left open at the forward tip. A soft-point bullet is intended to expand upon striking flesh to cause a wound diameter greater than the bullet diameter. Jacketed soft point bullets are usually abbreviated ''JSP'' in the ammunition and reloading industry. The use of soft-point bullets in warfare is a violation of the Hague Convention of 1899, declaration IV, 3. Evolution Lead-alloy bullets used with gunpowder firearms were unsatisfactory at the bullet velocities available from rifles loaded with nitrocellulose propellants such as cordite. By the late 19th century, lead-alloy bullets were being enclosed within a jacket of stronger mild steel or copper alloyed with nickel or zinc to reliably impart stabilizing rotation in rifled barrels. The lead-alloy core was swaged into a cup of the stronger metal covering the front and sides o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hollow Point Bullet
A hollow-point bullet is a type of expanding bullet which expands on impact with a soft target, transferring more or all of the projectile's energy into the target over a shorter distance. Hollow-point bullets are used for controlled penetration, where overpenetration could cause collateral damage (such as aboard an aircraft). In target shooting, they are used for greater accuracy due to the larger meplat. They are more accurate and predictable compared to pointed bullets which, despite having a higher ballistic coefficient (BC), are more sensitive to bullet harmonic characteristics and wind deflection. Plastic-tipped bullets are a type of (rifle) bullet meant to confer the aerodynamic advantage of the Spitzer bullet (for example, see very-low-drag bullet) and the stopping power of hollow-point bullets. Gunshot wounds from hollow-point bullets can be very painful; due to this, they have been banned from use in wartime. They may leave fragments difficult to remo ...

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 kilogram-force per square meter (kgf/m2) or pounds per square inch (lb/in2) (where 1 lb/in2 corresponds to ). Formulas General :C_\text = \frac = \frac where: *''C''b,physics, ballistic coefficient as used in physics and engineering *''m'', mass *''A'', cross-sectional area *''C''d, drag coefficient *\rho, density *\ell, characteristic body length Ballistics The formula for calculating the ballistic coefficient for small and large arms projectiles ''only'' is as follows: :C_\text = \frac where: *''C''b,projectile, ballistic coefficient as used in point mass trajectory from the Siacci method (less than 20 degrees). *''m'', mass of bullet *' ...

Internal Ballistics
Internal ballistics (also interior ballistics), a subfield of ballistics, is the study of the propulsion of a projectile. In guns, internal ballistics covers the time from the propellant's ignition until the projectile exits the gun barrel. The study of internal ballistics is important to designers and users of firearms of all types, from small-bore rifles and pistols, to artillery. For rocket-propelled projectiles, internal ballistics covers the period during which a rocket motor is providing thrust. General concepts Interior ballistics can be considered in three time periods: *Lock time - the time from sear release until the primer is struck *Ignition time - the time from when the primer is struck until the projectile starts to move *Barrel time - the time from when the projectile starts to move until it exits the barrel. The burning firearm propellant produces energy in the form of hot gases that raise the chamber pressure which applies a force on the base of the projectile, ...

Semiwadcutter
A semiwadcutter (SWC) or flat-nose is a type of all-purpose bullet commonly used in revolvers. The SWC combines features of the traditional round-nosed bullets and the wadcutter bullets used in target shooting, and is used in both revolver and rifle cartridges for hunting, target shooting and plinking. Full wadcutters frequently have problems reliably feeding from the magazines of semi-automatic pistols, so SWCs may be used when a true WC is desired but cannot be used for this reason. The semiwadcutter design consists of a roughly conical shape with the tip truncated flat (called a '' meplat''), sitting on a cylinder (''A'' at right). The base of the cone is slightly smaller in diameter than the cylinder, leaving a sharp shoulder. The flat nose punches a clean hole in the target, rather than stretching/tearing it like a round nose bullet would, and the sharp shoulder enlarges the hole neatly, allowing easy and accurate scoring of the target. A hunting flat nosed cast bullet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S&W Model 29
The Smith & Wesson Model 29 is a six-shot, double-action revolver chambered for the .44 Magnum cartridge and manufactured by the United States company Smith & Wesson. The Model 29 was offered with barrels as standard models. Other barrel lengths were available either by special order from Smith & Wesson's Custom Shop or custom built by gunsmiths. The barreled variant had a full-length underlug. Finish options available included a highly polished blued or nickel-plated surface. At the time of its introduction, the Model 29 was the most powerful production handgun, although it was later overtaken by handguns chambered for the even larger .454 Casull, .50 Action Express, and .500 S&W Magnum cartridges. It was made famous worldwide by association with the fictional character "Dirty Harry" Callahan. Design The Model 29 will chamber and fire .44 Special and .44 Russian cartridges, as the .44 Magnum was developed from the .44 Special and the .44 Special was developed from ...

38-40
The .38-40 Winchester (10.17x33mmR) is actually a .40 caliber (10 mm) intermediate cartridge shooting .401 in (10.2 mm) caliber bullets. The cartridge was introduced by Winchester in 1874 and is derived from their .44-40 Winchester. This cartridge was introduced for rifles, but in its reintroduction for cowboy action shooting it has seen some popularity as a revolver cartridge. It is not particularly well suited to hunting larger game, but it was popular when it was introduced, along with the previous .44-40 Winchester, for deer hunting. It can be used successfully on smaller game animals, and for self-defense. Current loadings are intended for revolvers. Design and history It is unclear why this cartridge was introduced, as it is very similar to the .44-40 from which it was derived. It has approximately less muzzle energy, and has a muzzle velocity about less than the .44-40. The bullet differs by only .026 inches in bullet diameter and in standard bullet weight ...
