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 feeding from magazines reliably in semi-automatics, 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. The SWC design offers better external ballis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wadcutter
A wadcutter is a special-purpose flat-fronted bullet specifically designed for shooting paper targets, usually at close range and at subsonic velocities typically under approximately 900 ft/s (274 m/s). Wadcutters have also found favor for use in self-defense guns, such as .38 caliber snubnosed revolvers, where, due to short barrel lengths, maximum bullet velocities are usually low, typically under 900 ft/s (274 m/s), and improved lethality is desired. Wadcutters are often used in handgun and airgun competitions. Bullet profile A wadcutter has a flat or nearly flat front that is typically as wide as the caliber size or only slightly smaller in diameter than caliber size. For target shooting, a wadcutter cuts a very clean hole through the paper target, making it easier to score and ideally reducing errors in scoring the target in the favor of the shooter. Because the flat nosed bullet is not well suited for feeding out of a magazine, wadcutters are normally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullet
A bullet is a kinetic projectile, a component of firearm ammunition that is shot from a gun barrel. Bullets are made of a variety of materials, such as copper, lead, steel, polymer, rubber and even wax. Bullets are made in various shapes and constructions (depending on the intended applications), including specialized functions such as hunting, target shooting, training and combat. Bullets are often tapered, making them more aerodynamic. Bullet sizes are expressed by their weights and diameters (referred to as "calibers") in both imperial and metric measurement systems. For example: 55 grain .223 caliber bullets are of the same weight and caliber as 3.56 gram 5.56mm caliber bullets. Bullets do not normally contain explosives but strike or damage the intended target by transferring kinetic energy upon impact and penetration. Bullets shot by firearms can be used for target practice or hunting. Description The term ''bullet'' is from Middle French, originating as the diminutiv ...

357 Magnum
The .357 Smith & Wesson Magnum, .357 S&W Magnum, .357 Magnum, or 9×33mmR as it is known in unofficial metric designation, is a smokeless powder cartridge with a 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. The .357 Magnum cartridge is based upon Smith & Wesson's earlier .38 Special cartridge. It was introduced in 1935, and its use has since become widespread. This cartridge began the " Magnum era" of handgun ammunition. The "Magnum era" began with the .375 H&H rifle cartridge, spreading to handguns with the .357 Magnum. Design The .357 Magnum was collaboratively developed over a period in the early to mid-1930s by a group of individuals in a direct response to Colt's .38 Super Automatic. At the time, the .38 Super was the only American pistol cartridge capable of defeating automobile cover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elmer Keith
Elmer Merrifield Keith (March 8, 1899 – February 12, 1984) was an American rancher, firearms enthusiast, and author. Keith was instrumental in the development of the first magnum revolver cartridge, the .357 Magnum, as well as the later .44 Magnum and .41 Magnum 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. In ''The Phantom Of Phu Bai'', a biography of USMC Scout Sniper Eric England written by Joseph B. Turner, one chapter is about Elmer Keith and his influence on the shooting community. Mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meplat
The meplat (from the French word "''méplat''" meaning "flat surface of a cylinder") is the technical term for the flat or open tip on the nose of a bullet. The shape of the meplat is important in determining how the bullet moves through the air. In particular the size and shape of the meplat has a significant effect on the ballistic coefficient of a bullet. Theory ''Trimming'' the meplat (cutting the tip of the bullet, thus increasing its area) decreases the bullet's ballistic coefficient, increasing drag and making it more susceptible to wind drift. So even though the grouping will be tighter, the time of flight and wind drift will be slightly greater. ''Pointing'' the meplat (reducing its area) involves pressing the bullets into a special die. This decreases the size of the meplat which increases the ballistic coefficient and reduces drag, time of flight and wind drift. Some target shooters sort their bullets by weight, point their bullets and then trim them to the same mepl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plinking
Plinking refers to informal target shooting done for pleasure, typically at non-standard targets such as tin cans, logs, bottles, or any other homemade or naturally occurring target. Practice In contrast to shooting done at established target ranges, plinking is generally done at home, in an open field, or other private land for no fee. The term ''plinking'' is an onomatopoeia of the sharp, metallic sound (or "plink") that a projectile makes when hitting a metal target such as a tin can. The most common caliber used for plinking is the .22 Long Rifle rimfire cartridge, since these rounds are relatively inexpensive and have a low recoil; however, any caliber can be used in plinking, and it is not unusual to see a person plinking with a full power rifle or pistol. Air guns and airsoft guns are also used, often for cost or safety reasons or because they are subject to less stringent regulation - a similar practice with a bow and arrow is usually termed "stump shooting".

Revolver
A revolver (also called a wheel gun) is a repeating firearm, repeating handgun that has at least one gun barrel, barrel and uses a revolving cylinder (firearms), cylinder containing multiple chamber (firearms), chambers (each holding a single cartridge (firearms), cartridge) for firing. Because most revolver models hold up to six rounds of cartridge before needing to reload, revolvers are also commonly called six shooters. Before firing, cocking the revolver's hammer (firearms), hammer partially rotates the cylinder, indexing (motion), indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. The hammer cocking in nearly all revolvers are manually driven, and can be achieved either by the user using the thumb to directly pull back the hammer (as in trigger (firearms)#Single-action, single-action), via internal linkage (mechanical), linkage relaying the force of the trigger-pull (as in trigger (firearms)#Double-actio ...

45 ACP
The .45 ACP ( Automatic Colt Pistol) or .45 Auto (11.43×23mm) is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun. The standard issue military .45 ACP round uses a 230- grain (14.9 g) round nose projectile that travels at approximately 830 feet per second (250 m/s) when fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating of , compared to for both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullseye Shooting
Bullseye shooting is a category of shooting sport disciplines where the objective is to score points with carefully placed precision fire by hitting a target as close to its center as possible. The name refers to the target center's nickname — the " bull's eye". In Scandinavia, this type of shooting competition is referred to as Range-Shooting ( da, baneskydning, no, baneskyting, sv, banskytte), as it usually takes place at dedicated shooting range. A large emphasis is put on accuracy and precision through steady breath, sight picture and trigger control, and fixed and relatively long time limits give competitors time to concentrate for a perfect shot. An example of bullseye shooting competitions is the ISSF pistol and rifle events, but there are also many other national and international disciplines which can be classified as bullseye shooting, e.g., NRA Precision Pistol competitions in the United States. Matches are normally held at permanent shooting ranges where the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
