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 ...

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 ...
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 ...
He is credited with a number of contributions to the field of terminal ballistics, including: [6] [7] [8] Developing and testing improved media in which the effects of bullet wounds could be simulated. This led to the widespread acceptance of 10% ballistic gelatin for evaluating penetration and expansion of projectiles.
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.
[4] [5] [6] The Kistler ballistic pressure measurement sensor 6215 has a maximum working pressure of 600 MPa (87,023 psi) and is mounted recessed inside the cartridge case (the face of high-pressure sensor does not contact the cartridge case) and requires that the test cartridge case have a hole drilled in it prior to testing. The test ...
There has been much debate regarding the bullet's unreliable expansion when fired through clothing or media other than ballistic gelatin. The bullet typically displays very rapid expansion, resulting in a larger but more shallow wound channel than would be typical from most other bullet configurations in the same caliber and of similar weight.
