The .45-70 Government Ammo was designed and developed in 1873. The cartridge was created to replace the stopgap .50-70 Government Ammo. The .45-70 Government Ammo has the minimum accuracy of 4-inch drop at 100 yards, but the slow and heavy bullet in longer ranges would have a rainbow trajectory. Still, skilled shooters can easily hit targets with ease using the .45-70 Government Ammo. This cartridge was even used in several Gatling gun models, especially on US Navy warships in the 1880s and 1890s. The .45-70 Government Ammo is s super hit amongst the sportsmen, and that's the main reason this bullet is still alive today. The overall length of the .45-70 Government Ammo is 53.5mm, while the bullet diameter measures 11.6mm. One variant of the .45-70 Government Ammo is loaded with 300-grain that can travel at a velocity of 2,275 feet per second and produce an energy level of 3,449 ft.lbf.
To fill out the gap left by the 50.70 Government Ammo, the US Army's Springfield Armory designed and developed the .45-70 Government Ammo.
The traditional 405-grain variant of the .45-70 Government ammo can take down any North American big game species within its effective range. Thanks to its low velocity, the .45-70 Government Ammo doesn't destroy the edible meat on the delicate game like deer. The .45-70 Government Ammo holds the potential of taking down the big five African game in the range of 1,000 yards.
30-40 Krag Ammo
The .30-40 Krag Ammo was designed by Krag Jorgensen and developed by the US armed forces in the early 1890s. It is the first smokeless powder round adopted by the army, and it retained a caliber-charge naming system of the earlier cartridges.
It earned its title of the first small-bore military centerfire cartridge due to its small caliber bullet. All previous metallic military rifle ammunitions were black powder-powered and had large capacity cases. However, in 1899, the US Army requested an improved military rifle with matching cartridge, and the .30-40 Krag Ammo was born. Although this cartridge didn’t last long as the US Army standard cartridge, the .30-40 Krag will remain the first American military rifle designed from the onset to use smokeless powder.
From the beginning, the .30-40 Krag Ammo was famous for hunting and chambered in several firearms. Because of its efficiency, the .30-40 Krag Ammo achieved a higher velocity than was previously possible when it was created. Therefore, hunters jumped at the chance to use smaller caliber lighter and far more aerodynamic bullets. In 1899, someone used it to shoot the world-record Rocky Mountain elk. This record stood till the second half of the 20th century.
The Springfield Amory was known to produce several variants of the .30-40 Krag Ammo for the army till it was supplanted. The first .30-40 Krag ammo ballistics were a 220-grain bullet and 2,00 fps. However, the modern .30-40 Krag ammo ballistics are a 180-grain bullet at 2,430 fps. That’s why it is ideal for hunting games like deer and elk at either a short or medium range.
