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 ...
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.
In tests against ballistic gelatin, a 185-grain (12.0 g) hollow point traveling at 1,050 feet per second (320 m/s) expanded to about .76 inches (19 mm). This is a significantly large permanent wound cavity for a handgun projectile. For those who follow the energy dump and/or hydrostatic shock theories of wounding ballistics, this is ideal.
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.
The Thompson–LaGarde Tests have since been criticized as being "highly unscientific" and producing a recommendation unsupported by the test results. [7] Others, notably Julian Hatcher [9] and Jeff Cooper, [10] regarded the tests as well conducted, and the recommendation as fully supported by the evidence available to the board, and empirical evidence subsequently available concerning ...
In one test, the 300 grain (19 g) jacketed flatpoint (JFP) gave a 25-yard group of 2.56 inches, and the 300-grain Jacketed hollow point (JHP) and 275-grain JHP gave a 25-yard group of 2.3 inches. [3] The penetration in gelatin (but not necessarily the kinetic energy) of the .50 GI is significantly different than the .45 ACP.
North Korea fired a long-range ballistic missile into the sea off its east coast on Thursday, South Korea and Japan said, a day after Seoul reported the North was making preparations to test ...
Ballistic gelatin is a good match to muscle tissue, for both humans and game animals. It does not provide any simulation of the skin, fat layers, organs, or any other structures, but then the purpose of ballistic gelatin is not to provide a perfect match, but rather to provide a consistent, repeatable medium for comparative testing.
