Number of manufacturers producing complete cartridges - e.g. Norma, RWS, Hornady, Winchester, Federal, Remington, Sellier & Bellot, Prvi Partizan. May be none for obsolete and wildcat cartridges . H/R: Handgun (H) or rifle (R) - dominant usage of the cartridge (although several dual-purpose cartridges exist)
The .450 Marlin is a firearms cartridge designed as a modernized equivalent to the .45-70 cartridge. It was designed by a joint team of Marlin and Hornady engineers headed by Hornady's Mitch Mittelstaedt, [4] and was released in 2000, with cartridges manufactured by Hornady and rifles manufactured by Marlin, mainly the Model 1895M levergun.
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 ...
Joyce W. Hornady began manufacturing bullets in the spring of 1949 with a .30 caliber 150 gr (9.7 g) spire point selling for $4.50 per hundred. Within a year Hornady was producing thirteen different bullets in five different calibers. The Korean War caused material shortages limiting early production.
The .450 Bushmaster is descended from the Thumper concept popularized by the gun writer Jeff Cooper.Cooper was dissatisfied with the small-diameter 5.56×45mm NATO (.223 Remington) of the AR-15, and envisioned a need for a large bore (.44 cal or greater) cartridge in a semi-automatic rifle to provide one-shot kills on big-game animals at 250 yards.
Dug out my internal ballistics software and plugged in the .45-70-405 data based on the Sandy Hook trials and a .308 long range load, and got the following: The scale exagerates the slope a bit--the .45-70 is actually traveling downwards at about a 20 degree angle when it hits--but the .308 is only doing about a 3.6 degree angle.
For comparison, Hornady's 9249 load for the .500 S&W Magnum cartridge offers slightly less energy at the muzzle, achieving 2,868 ft⋅lbf (3,888 J) by driving a 300 grain (19 g) FTX bullet at 2,075 ft/s (632 m/s). Buffalo Bore's loading for the .500 S&W cartridge offers much less energy at the muzzle, achieving only 2,579 ft⋅lbf (3,497 J) by ...
These figures compare favorably to Smith & Wesson's newest contender for most powerful commercial sporting handgun cartridge, the .460 S&W Magnum, which can launch a 325 gr (21.1 g) at 1,650 ft/s (500 m/s) or a 395 gr (25.6 g) at 1,525 ft/s (465 m/s). The .500 S&W Magnum comes into its own when used with heavier bullets, particularly those with ...
