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.
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.
For an example of attempts to provide simulation of structure, take a look at the tests done by John Linebaugh at the Big Bore Sixgun Seminar. They use wet newspaper, which is a tougher medium than gelatin, and they test for DEEP penetration--the Garrett Hammerhead .45-70 load penetrates 55" of wet newspaper. In some tests they also throw in ...
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 ...
[41] [42] Maintainers of these databases recommend that every recovered firearm be test fired and the resulting known exemplar be uploaded into the database. [43] In the 1990s, there were two databases that were formed for storage of pictures of shell casings and bullets in gun crimes. The first was the Drugfire system which was used by the FBI.
The .500 Bushwhacker is a .50 caliber semi-rimmed revolver cartridge developed by TII Armory for the Magnum Research BFR revolvers. It is currently the most powerful revolver cartridge in the world, offering a similar level of ballistic performance to African stopping rifles, such as the .416 Rigby and .470 Nitro Express.
