Their interchange is, however, considered safe by the Sporting Arms, the.308 Winchester has 3.64 ml cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt action rifles and machine guns alike, all dimensions in millimeters and inches. Americans would define the angle at alpha/2 =20 degrees. The common rifling twist rate for this cartridge is 305 mm,4 grooves, Ø lands =7.62 mm, Ø grooves =7.82 mm, land width =4.47 mm and the primer type is large rifle. Rulings the.308 Winchester can handle up to 415.00 MPa Pmax piezo pressure, regulated countries every rifle cartridge combo has to be proofed at 125% of this maximum C. I. P. pressure to certify for sale to consumers. This means that.308 Winchester chambered arms in C. I. P, regulated countries are currently proof tested at 519.00 MPa PE piezo pressure. North American SAAMI maximum pressure for the 308 Winchester is 62,000 PSI, the.308 Winchester is one of the most popular hunting cartridges in the United States, and possibly the world.

.338 Lapua Magnum
The.338 Lapua Magnum is a rimless, bottlenecked, centerfire rifle cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers and it was used in the Afghanistan War and the Iraq War. As a result of this, it more widely available. The loaded cartridge is 14.93 mm in diameter and 93.5 mm long and it can penetrate better-than-standard military body armour at ranges up to 1,000 metres and has a maximum effective range of about 1,750 metres. British military issue overpressure.338 Lapua Magnum cartridges with a 91.4 mm overall length, in addition to its military role, it is increasingly used by hunters and civilian long-range shooting enthusiasts. In Namibia the.338 Lapua Magnum is legal for hunting Africas Big five game if the loads have ≥5,400 J muzzle energy, the.416 Rigby is an English big game cartridge that was designed to accommodate 325 MPa pressures. One of the disadvantages of these old cartridge cases, which were intended for firing cordite charges instead of modern smokeless powder, is the thickness of the sidewall just forward of the web, during ignition, the cartridges base, forward to the bolt face, is not supported. The case is back against the bolt face, which results in the stretching of the case. When the sidewall resists the outward expansion against the chamber, the pressure stretches the case, thereby increasing its length, RAI found that the BELL cases did not fulfill the requirements. Pressed by military deadlines RAI looked for another producer and contacted Lapua of Finland in 1984. RAI was forced to out of the program due to financial difficulties. Subsequently, Lapua of Finland put this cartridge into limited production, the. 338/416 rifle program was later canceled when the contractors were unable to make the cartridge meet the projects velocity target of 914 m/s for a 16.2 g bullet, due to weak brass cases. Lapua opted to redesign the. 338/416 cartridge, in the new case design, particular attention was directed toward thickening and metallurgically strengthening the cases web and sidewall immediately forward of the web. In modern solid head cases, the hardness of the brass is the factor that determines a cases pressure limit before undergoing plastic deformation. Lapua tackled this problem by creating a hardness distribution ranging from the head and web to the mouth as well as a strengthened case web and sidewall immediately forward of the web. This resulted in a very pressure resistant case, allowing it to operate at high pressure, Lapua also designed a 16. 2-gram.338 calibre Lock Base B408 full metal jacket bullet, modeled after its.30 calibre Lock Base bullet configuration. The result was the.338 Lapua Magnum cartridge which was registered with C. I. P. in 1989, with the procurement by the Dutch Army, the cartridge became NATO codified. The.338 Lapua Magnum fills the gap between weapons chambered for standard military rounds such as the 7. 62×51mm NATO and large, weighty rifles firing the.50 BMG cartridge
The Mini-14 is a lightweight.223 caliber semi-automatic rifle manufactured by Sturm, Ruger & Co. that is popular with law enforcement, security personnel, hunters, ranchers and target shooters. It is made in a number of variants including the Ranch Rifle with a scope base on the receiver, the Mini Thirty which is chambered for 7. 62×39mm, and the AC-556. The Mini-14 was first introduced in 1973 by Sturm, Ruger & Co, the name Mini-14 was coined because it resembles a smaller version of the military M14 rifle. Designed by L. James Sullivan and William B, Ruger, it incorporated numerous innovations and cost-saving engineering changes. The Mini-14 rifle employs an investment cast, heat-treated receiver and is similar to the M1 Garand rifle, with a self-cleaning. Initial rifles were produced with a complex, exposed bolt hold open device with no button for manual engagement, stocks were somewhat angular and heat shields were made of wood. These rifles, with serial number prefixes before 181, were tooled and redesigned with a new stock, new bolt hold-open mechanism, the original Mini-14 rifle had a rear aperture sight with large protective wings, and no integral scope bases. In 1982, Ruger introduced the Ranch Rifle with a scope base on the receiver. It introduced a heat shield and ejected spent cartridge cases at a lower angle to avoid hitting low-mounted scopes. In 1987, Ruger introduced the Mini Thirty rifle chambered for the Russian 7. 62×39mm cartridge, at the time, large quantities of surplus military ammunition were being imported into the United States at rock bottom prices. Also, the 7. 62×39mm is ballistically similar to the. 30-30 Winchester cartridge, as a result, the Mini Thirty proved to be an effective deer rifle. The design was overhauled to improve accuracy and update the styling while at the same time reducing production costs, the standard Mini-14 was discontinued and the name became the family name for all Mini-14 type rifles. These upgraded rifles have serial numbers beginning with 580 and are referred to as 580 series Ranch Rifles. They have new iron sights and a gas system designed to reduce barrel vibration and are capable of shooting 2 inch groups at 100 yards or 2 minute of angle accuracy. Sometime between 2007 and 2008, Ruger added a heavier tapered barrel to the Mini series, the heavier barrel had an overall larger diameter with the barrel visibly becoming thicker in the final inches as the barrel approaches the gas block from the muzzle. These changes combined with tighter tolerances result in greater potential accuracy, all Mini-14 type rifles are available in stainless steel or blued finish with hardwood, synthetic, or laminated stocks with 16. 12-inch or 18. 5-inch barrels. Most Mini-14s have a classic sporter appearance in contrast to comparable autoloading rifles such as the AK-47, however, Ruger now offers some Mini-14 rifles in a black ATI-brand adjustable folding stock with a pistol grip. Also, Ruger factory-made 5-, 10-, 20- and 30-round steel magazines are available along with numerous aftermarket options
The SR-556 is a semi-automatic rifle carbine manufactured by U. S. firearms company Sturm, Ruger & Company, Inc. The rifle was introduced in 2009, marking Rugers entry into the popular AR-15 market, and it would continue with a.308 AR-10 variant and it is one of several new AR-15 rifles to use gas piston operation. In January 2016 Ruger discontinued all SR-556 rifles and introduced a new Takedown variant with a lightweight Keymod handguard, the rifle features a patent-pending, two stage piston mechanism as opposed to the standard AR-15 direct impingement system.

The SR-556SC comes with three 10-round magazines and does not have the flash hider or collapsible stock, making it compliant in several states with restrictive assault rifle laws. The barrel is 409 millimetres, chrome lined, and features a six groove, in August 2010, Ruger announced that the rifle would be offered in the 6. 8mm Remington SPC cartridge. Pricing suggests that its intended to compete with other entry level AR-15s such as the Smith & Wesson M&P15 Sport, Rugers introduction of the SR-556 was met with some criticism for its high price tag. The SR-556 was also criticized for its weight than other AR-15s.
