The .440 Cor-Bon is a large-caliber handgun cartridge, first produced by Cor-Bon in 1998. Although it looks similar to a .357 SIG, this cartridge was designed after being necked down from an existing cartridge, the .50 AE to accept a .44-caliber (.429 in) (10.89 mm) bullet. This is fairly typical in the wildcat cartridge industry.
The most common current loading is a 200-gr bullet at 1190 ft/s. [3] By 1942, more modern cartridges had all but eclipsed the .44-40, but it regained some popularity in the 1950s and 1960s when Colt began once again to manufacture the Single Action Army and Frontier. [8]
[24] [25] The limiting factor of the .44 Magnum cartridge is not terminal ballistics. When fired from a 6 in (152 mm) revolver, a typically loaded .44 Magnum 240 gr (16 g) bullet will have more impact energy at 150 yd (137 m) than a 246 gr (15.9 g) .44 Special has at the muzzle, when fired from the same weapon.

The .429 DE is a .50 AE case that is necked down to accept .429-diameter (10.9mm) bullets used in the .44 Magnum.The cartridge features a 25% increase in velocity and 45% increase of energy over a standard 240-grain .44 Magnum load of 1,285 ft⋅lbf (1,742 J) at 100 yd (91 m). [2]
The heeled bullets make the cartridge incompatible with .44 Russian, .44 Special, and .44 Magnum, which was made larger in diameter and longer to cover the exposed part of the bullet. Its power resembles the .41 Long Colt , [ 1 ] .32-20 Winchester , [ 2 ] or .44-40 Winchester , [ 3 ] and it could be used to hunt small game at short range.
This created a cartridge case stronger than the .45 Winchester Magnum cartridge case. The .40 Super cartridge case was designed for a balance of strength and powder capacity. To maximize bullet pull and overall feeding characteristics, the case has a neck length of .175 in. The shoulder angle is an optimum 25 degrees.
The .240 Weatherby Magnum was developed in 1968 by Roy Weatherby. In the development of his own .240in/6 mm cartridge, Weatherby was significantly influenced by both the success and the limitations of the .244 H&H Magnum cartridge devised in England by his friend and colleague David Lloyd. It was the last cartridge to be designed by Roy ...
The .40 S&W (10.2×22mm) is a rimless pistol cartridge developed jointly by American firearms manufacturers Smith & Wesson and Winchester in 1990. [3] The .40 S&W was developed as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9 mm size) semi ...
