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 ...
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.
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 ...
While this venture was a success, Linebaugh was intrigued by Wheeler and Topping's work, and decided to pursue a .50 caliber handgun cartridge of his own. [ 1 ] The cartridge case itself was designed by cutting off the .348 Winchester case to 1.405 in (35.7 mm), turning the rim to a diameter of .610 in (15.5 mm) and opening the case mouth to ...
For example, a popular caliber in the United States is .45 ACP. It is among the largest practical handgun calibers in use, featuring a .452 inches (11.5 mm) diameter bullet. With well-made expanding ammunition, a .452 bullet often expands to .70 caliber or larger. With a 9 mm Luger cartridge, the normal .355 bullet may expand to .50 or larger ...
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.
