The 470 Nitro Express is a rifle cartridge designed in England by Joseph Lang for hunting hazardous animals in Africa and India. Lang's created it as a substitute for the.450 Nitro Express when the.450 NE was prohibited in a number of countries, including India. After the.450 Nitro Express was outlawed in various countries, including India, Lang's produced the as a substitute. The 470 Nitro Express remains the most popular of all the Nitro Express cartridges, with both ammo and parts widely accessible.
The ballistics of the 470 Nitro Express are quite similar to those of the other Nitro Express cartridges, which were meant to duplicate the old.450 NE formula, which is a 480 or 500-grain bullet travelling at 2,050 to 2,200 fps. The.470 Nitro Express, like many of its cousins with comparable power ratings, has a significant amount of recoil. In contrast to the harsh slap of the hyper-velocity magnums, the recoil is a traditional 'push.'
Without giving it too much thought, this is an excellent big game cartridge, and given the enormous number of firearms chambered in.470 NE, ammo is seldom a problem to find. The 470 Nitro Express is a monster in terms of performance, and a genuine big game backup. Some may be surprised to learn that, despite being a large 500-grain projectile, a zero at 50 yards will only drop the bullet half an inch at 100 yards, which is likely the maximum range for which you will ever need to utilize such a calibre. It comes with a choice of loaded rounds, so bullet performance is not an issue.
The 50 Browning Machine Gun, sometimes known as the 50 BMG, is a 50 in (12.7 mm) caliber cartridge that was created for the M2 Browning heavy machine gun in the late 1910s and entered formal service in 1921. The machine gun was initially produced during World War I, and despite being cumbersome, the tank began to find its place on the battlefield—it was also resistant to most rifle and artillery shots.
The 50 BMG cartridge has a 290-gram capacity (19 g). The round is a scaled-up version of the 30-06 Springfield, but it has a case wall with a long taper to make feeding and extraction easier in different guns. This cartridge's rifling twist rate is 1 in 15 in (380 mm), with eight lands and grooves.
The 50 Browning Machine Gun is employed in anti-materiel rifles in addition to the M2 Browning heavy machine gun. There is a wide range of ammunition available, and match grade ammunition has boosted the use of 50 caliber rifles by allowing for more precise firing than lesser quality rounds. During WWII, the 50 BMG was principally utilized for anti-aircraft duties in the M2 Browning machine gun, both in its "light barrel" aircraft mount form and the "heavy barrel" (HB) version on ground vehicles.
Depending on the powder and bullet type, as well as the weapon from which it is shot, the 50 BMG round may create between 10,000 and 15,000 foot-pounds force (14,000 and 20,000 J). The 50 BMG's trajectory suffers less "drift" from cross-winds than smaller and lighter calibers due to the high ballistic coefficient of the bullet, making it an excellent option for high-powered sniper rifles.
