Plastic-tipped Bullet
A plastic-tipped bullet is a type of hollow-point bullet tipped with a nose cone made of synthetic polymer to give it a pointed spitzer-like shape. The plastic tip drives into the hollow point upon impact, causing the bullet to expand, which increases lethality. These bullets are typically designed for rifles and single-shot handguns, improving aerodynamics for longer, more accurate flights. Some companies also produce such bullets for semi-automatic pistols to improve ammunition feeding and prevent jams. The term "Ballistic Tip" is trademarked by Nosler, with other companies like Hornady and Sierra Bullets also producing similar bullets. Design and use The bullets consist of a fairly normal hollow-point bullet with the frontal cavity filled in by hard plastic, which is molded into a streamlined shape. Most tips are made of polyoxymethylene, although some manufacturers have used polyester urethane- methylenebis(phenylisocyanate) copolymer. Upon impact, the plastic ...

Copolymer
In polymer chemistry, a copolymer is a polymer derived from more than one species of monomer. The polymerization of monomers into copolymers is called copolymerization. Copolymers obtained from the copolymerization of two monomer species are sometimes called ''bipolymers''. Those obtained from three and four monomers are called ''terpolymers'' and ''quaterpolymers'', respectively. Copolymers can be characterized by a variety of techniques such as NMR spectroscopy and size-exclusion chromatography to determine the molecular size, weight, properties, and composition of the material. Commercial copolymers include acrylonitrile butadiene styrene (ABS), styrene/butadiene co-polymer (SBR), nitrile rubber, styrene-acrylonitrile, styrene-isoprene-styrene (SIS) and ethylene-vinyl acetate, all of which are formed by chain-growth polymerization. Another production mechanism is step-growth polymerization, which is used to produce the nylon-12/6/66 copolymer of nylon 12, nylon 6 a ...

308 Winchester
The .308 Winchester is a smokeless powder Rim (firearms), rimless bottlenecked rifle Cartridge (firearms), 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 7.62×51mm NATO#Development, T65 series of experimental cartridges. The original experimental case design by the Frankford Arsenal was designated "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 walls. The later T65 iterations were lengthened compared to the original T65 case and provided a ballistic performance roughly equal to the U.S. mi ...

30-30 Winchester
The .30-30 Winchester / 7.8x51mmR (officially named the .30 Winchester Center Fire or .30 WCF) cartridge was first marketed for the Winchester Model 1894 lever-action rifle in 1895.Load Guide data from Accurate Powder. The .30-30 (pronounced "thirty-thirty"), as it is most commonly known, along with the .25-35 Winchester, was offered that year as the United States' first small-bore sporting rifle cartridges designed for smokeless powder. Since its introduction, it has been utilized alongside the development of flatter shooting cartridges, most prominently those derived from designs subsidized by interest in military expenditures. (Examples: ..303 British, 303 British, .30-06 Springfield, .30-06, and 6.5×55mm Swedish, 6.5x55 Swedish) The .30-30 has remained in widespread use almost entirely ...

204 Ruger
The .204 Ruger / 5.2x47mm is a centerfire rifle cartridge developed by Hornady and Ruger. At the time of its introduction in 2004, the .204 Ruger was the second-highest velocity commercially produced ammunition and the only centerfire cartridge produced commercially for bullets of .204 inch/ 5 mm caliber. Characteristics The .204 Ruger was developed from the .222 Remington Magnum, which has the second-largest case capacity in the family that began with the .222 Remington. Only the European 5.6×50mm Magnum is larger, which itself is a lengthened version of the .222 Remington Magnum. The .222 Remington Magnum provides about 5% more usable (below the neck) case capacity than the most popular member of the family, the NATO 5.56×45mm (.223 Remington). To make the .204 Ruger, the .222 Remington Magnum case was necked down to .204 inches (5 mm) and its shoulder moved forward and angle increased to 30 degrees. Bullets available in .204 caliber range from 24 to 55 grains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
17 HMR
.17 Hornady Magnum Rimfire, commonly known as the .17 HMR, is a rimfire rifle cartridge developed by Hornady in 2002. It was developed by necking down a .22 Winchester Magnum Rimfire case to take a .17 caliber (4.5mm) projectile. Commonly loaded with a 17 grain (1.1 g) projectile, it can deliver muzzle velocities in excess of 775 m/s (2,650 ft/s). Development The .17 HMR round is similar to rounds developed by dedicated rimfire wildcatters who worked to create a rimfire cartridge with an exceptionally flat trajectory. These wildcatters were seeking to match the ballistics of the obsolete 5mm Remington Rimfire Magnum, which was made from 1970 to 1974, and was to that point the fastest rimfire cartridge ever produced. With 5 mm diameter barrels and bullets being virtually unavailable at the time (the 5mm RMR was the last commercial 5 mm round until the 2004 release of the centerfire .204 Ruger), the commercially available .17 caliber became their bullet of choice. The .22 W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Glaser Safety Slug
Glaser Safety Slug is a frangible bullet made by Cor-Bon/Glaser, a subsidiary of Dakota Ammo, an American ammunition company formerly based in Sturgis, South Dakota. The Glaser Safety Slug was developed by Jack Canon in 1975, the same year the company was founded by Armin Glaser. History The original round was a hand-made hollow-point bullet filled with No. 12 birdshot () with a flat polymer cap. To improve ballistic performance, a polymer-tipped round ball was introduced in 1987, and the current compressed core form was first sold in 1988. The formulation of the polymer was also changed in 1994 to improve fragmentation reliability. Performance The company produces bullets in calibers from .25 to .45 for pistols and from .223 to .30-06 for rifles. Each caliber comes in two forms, "blue" and "silver", the latter having greater penetrating power due to the use of no. 6 birdshot rather than no. 12. The projectile in the cartridge is of a lighter weight than more conventiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cor-Bon
Cor-Bon/Glaser LLC is a manufacturer of small arms ammunition. History Founded in Detroit, Michigan, 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. Product Lines Cor-bon produces several product lines of ammunition: *Original JHP *DPX *Performance Match *Urban Response *Hunting Lines *Multi-Purpose ...

Semi-automatic Pistol
A semi-automatic pistol (also called a self-loading pistol, autopistol, or autoloading pistol) is a repeating firearm, repeating handgun that automatically ejects and loads cartridge (firearms), cartridges in its chamber (firearms), chamber after every shot fired, but only one round of ammunition is fired each time the Trigger (firearms), trigger is pulled. The pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset manually, unlike the self-cycled firing mechanism in machine pistol, fully automatic pistols. A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt (firearm), bolt, which is usually housed inside the pistol slide, slide. After a round of ammunition is fired, the spent cartridge casing is extracted and ejected as the slide/bolt moves rearwards under recoil, the hammer (firearms), hammer/striker is cocked by the slide/bolt movement, and a ...

Pistol
A pistol is a type of handgun, characterised by a gun barrel, barrel with an integral chamber (firearms), chamber. The word "pistol" derives from the Middle French ''pistolet'' (), meaning a small gun or knife, and first appeared in the English language when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term to describe ''any'' type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder (firearms), cylinder housing multiple chambers) and the pocket gun, pocket-sized derringers (which are often multiple-barrel firearm, multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol. The older single-shot and lever-action pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment. Fully-automatic machine pistols are uncommon in civilian usage because of their generally poor recoil-controllability (due to the l ...

Rifle
A rifle is a long gun, long-barreled firearm designed for accurate shooting and higher stopping power, with a gun barrel, barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used in warfare, law enforcement, hunting and shooting sports, target shooting sports. The invention of rifling separated such firearms from the earlier smoothbore weapons (e.g., arquebuses, muskets, and other long guns), greatly elevating their accuracy and general effectiveness. The raised areas of a barrel's rifling are called ''lands''; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservatio ...
