In 1884, the US Ordnance Department increased the bullet weight of the 45–70 to 45–70–500, or a 45 caliber bullet, 70 grains of black powder, and a 500 grain bullet. [3] The new 45-70-500 loading was recorded with a muzzle velocity of 1315.7 feet, and generated 1525 ft lbs of energy at 100 yds, and 562.3 ft lbs of energy at 1,000 yards ...
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
According to the US Army Ordnance Department tests, the 45-70-405 was loaded to 19,000 psi, [4] while the 45-70-500 was loaded to 25,000 psi [2] The average accuracy of the Springfield Model 1873 was a circle with an average radius of 1.7 inches at 100 yards, corresponding to an ~3.4 MOA.
The Model 1874 rifles and carbines were available in a variety of calibers, including .45-70, .45-110, and .45-120. Action: Falling block: Rate of fire: 8–10 shots per minute: Muzzle velocity: 1,200 ft/s (370 m/s) Effective firing range: 1,000 yd (910 m) Maximum firing range: 3,000 yd (2,700 m) Feed system: Breech-loading: Sights: Open ladder ...
The Whisper family was developed as a line of accurate, multi-purpose cartridges using relatively heavy rifle bullets for a given caliber in subsonic loads. [1] [2] [3] The intention was to create an extremely accurate cartridge family for military, police, competition and specialized hunting markets that could also be easily sound suppressed.
This is the equivalent of +P loading as normal pressure for the .45 Colt is 14,000 psi (97 MPa). [11] In a section specifically titled "45 Colt for Ruger or Contender only" Speer makes reference to velocities up to 1,300 ft/s (400 m/s) with 200 gr (13 g) bullets. They also state that pressures do not exceed 25,000 psi (170 MPa) (CUP).
Cartridges were loaded with 45 grains (2.9 g) of black powder, and were also available as .56-52, .56-50, [15] and a wildcat .56-46, a necked down version of the original .56-56. Lugs indicates that the .50 calibre was the standard issue rifle, with a reduced diameter bullet to reduce the recoil and the risk of accidental magazine explosions ...
The No. 1 would later be produced in .44 rimfire, .45-70 Government, .44 Ballard Long, & .44 Ballard Extra Long. [2] This version along with the No. 5 + 1 ⁄ 2 Montana are known for being one of the main rifles used to hunt buffalo. [ 3 ]
