See: .45-70 at Two Miles: The Sandy Hook Tests of 1879), a new variation of the .45-70 cartridge was produced: the .45-70-500, which fired a heavier, 500-grain (32 g) bullet. The heavier bullet produced significantly superior ballistics and could reach ranges of 3,350 yd (3,060 m), which were beyond the maximum range of the .45-70-405.
Ballistic gelatin is traditionally a solution of gelatin powder in water. Ballistic gelatin closely simulates the density and viscosity of human and animal muscle tissue, and is used as a standardized medium for testing the terminal performance of firearms ammunition. While ballistic gelatin does not model the tensile strength of muscles or the ...
Smith & Wesson M&P in .38 Special produced in 1899 A .38 Special Jacketed Soft Point round Air Force issue Smith & Wesson Model 15-4 in .38 Special. In 1930, Smith & Wesson introduced a large-frame 38 Special revolver with a 5-inch barrel and fixed sights intended for police use, the Smith & Wesson 38/44 Heavy Duty.
The cartridge is based on the .45-70 Government case trimmed to 1.4 inches and loaded with .475-inch-diameter (12.1 mm) bullets. While dimensionally similar to the older .45 Silhouette cartridge, the .475 Linebaugh is loaded to considerably higher pressures, resulting in significantly different ballistic performance.
.38 TPC ammunition also meets FBI Protocol ballistic penetration requirements. In a comparative test with the .380 Auto Gold Hex ammunition, the .38 TPC caliber showed 14.5 inches (36.83 cm) of penetration into ballistic gelatin, therefore within the ideal range specified by the FBI in tests at distances of 10 feet (3 meters).
The Army had previously been using the .38 Long Colt, and the cartridge's relatively poor ballistics were highlighted during the Philippine–American War of 1899–1902, when reports from U.S. Army officers were received regarding the .38 bullet's inability to stop charges of frenzied Moro juramentados in the Moro Rebellion, even at extremely close ranges.
The second picture (Terminal performance comparison of 7.62×39mm and 5.45×39mm ammunition in ballistic gelatin) shows effects of full metal jacketed rifle rounds on ballistic soap obviously. Ballistic soap features nearly the same specifications like ballistic gelatine, so effects either in gelatine, soap or human soft tissue (muscle) can be ...
After test firing the guns, Goddard proved that the weapons were those used to kill the members of the North Side Gang, absolving the Chicago police department of all involvement. [12] The successful use of Goddard's technique resulted in the solidification of his place as the father of forensic firearm examination.
