7×57mm Mauser
[5] It was quickly improved to the Mauser Model 1893 featuring a new internal box magazine where the cartridges were stored in a staggered column.(Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings the 7×57mm case can handle up to 390.00 MPa (56,565 psi) Pmax piezo pressure.While various modern break-action and single-shot rifle and pistol designs have been developed that can reliably extract rimless cartridges, most of these date from the 1970s or later.The 7×57mm can offer very good penetrating ability due to a fast twist rate that enables it to fire long, heavy bullets with a high sectional density.[14] Bell selected the cartridge for moderate recoil, and relied on the 11.2-gram (172.8 gr) long round-nosed military full metal jacket bullets for penetration.Jack O'Connor also made extensive use of the round and remarked that "I think I have seen more game killed with fewer shots from this modest little cartridge than with any other.Corbett's writings mention using the .275 in a Rigby-made Mauser 1898 sporting rifle with attached torch to despatch the leopard on a dark summer night in May 1926.[citation needed] The 7×57 is able to handle a wide range of projectile weights, is easy to reload, has relatively mild recoil, and is accurate.[3] For the late 19th century, these ballistics were impressive, and the loading provided a fairly flat trajectory combined with excellent penetration.At the commencement of the American assault on the strategic Cuban city of Santiago, 750 Spanish troops defended positions on San Juan and Kettle hills.The attacking force numbered approximately 6,600 American soldiers, most of them armed with new smokeless-powder Krag–Jørgensen rifles in .30-40 Krag caliber,[17] and supported by artillery and Gatling gun fire.A U.S. board of investigation later concluded that the casualties were primarily due to the superior firepower of the Spanish Model 1893 Mauser rifles.[18] The .303 British cartridge at that time was still using cordite propellant, in contrast to the Mauser's higher-performance ballistite type smokeless powder.[20] The new spitzer bullet style was partially responsible for the cartridge's improved performance as it significantly reduced air drag within normal combat ranges and withstood higher accelerations in the barrel.This wildcat was designed to be easily made by rechambering existing firearms, and fire forming the ammunition to decrease body taper and increase shoulder angle, resulting in a higher case capacity with the trade-off of a smaller bullet.
