The .45 BPM is not a .460 S&W Magnum. The .45 BPM differs from the .460 S&W Magnum in several key areas. First, the .45 BPM is limited to a maximum C.O.L. (Cartridge Overall Length) of 2.140" [3] whereas the .460 S&W Magnum has a C.O.L. of 2.290". Second, the .45 BPM is a black-powder cartridge and can only contain either FFg or FFFg rated ...
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 ...
The fixed price for a traditional Hawken rifle was $22.50 - $25.00. Several of the fine engraved Hawken rifles sold for $38 between 1837-1842. A .70 caliber Hawken rifle, the largest caliber example known, that was once owned by Theodore Roosevelt and is set for auction in May of 2024 has an estimated auction value of US$55,000 to US$85,000.

Muzzleloading is the sport or pastime of firing muzzleloading guns. Muzzleloading guns, both antique and reproduction, are used for target shooting, hunting, historical re-enactment and historical research. The sport originated in the United States in the 1930s, just as the last original users and makers of muzzleloading arms were dying out ...

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.
For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
Pellet exiting muzzle, with formula for energy overlaid.. Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge.
