However, if the ammunition was tuned to the gun, the clear winner was the Python, which averaged just 43 millimetres (1.69 in) with its favored brand of ammunition. The Python was also by far the pickiest, however, turning in the largest groups at 154 and 102 millimetres (6.08 and 4.0 in) averages with its least favorite brands, for a standard ...
In January 2009 the Finnish ammunition manufacturer Lapua published Doppler radar tests derived drag coefficient data for most of their rifle projectiles. [1] [2] The predictive capabilities of the custom mode are based on actual bullet flight data derived from Doppler radar test sessions. With this data engineers can create algorithms that ...
This is especially true for arrow-type projectiles, which are long and thin for low drag efficiency, but too thin to shoot from a gun barrel of equal diameter to achieve high muzzle velocity. The physics of interior ballistics demonstrates why the use of a sabot is advantageous to achieve higher muzzle velocity with an arrow-type projectile ...
However, modern ballistic studies have shown no noticeable difference in terminal performance correlating to the recoil difference between typical minor and major handgun calibers. [7] On the other hand, the power factor requirement has been kept to award the greater challenge of marksmanship required by competitors to shoot firearms with more ...
There is wide variation in commercial ammunition. A 180 gr (12 g) bullet fired from .357 Magnum handgun can achieve a muzzle energy of 580 ft⋅lbf (790 J). A 110 gr (7.1 g) bullet fired from the same gun might only achieve 400 ft⋅lbf (540 J) of muzzle energy, depending upon the manufacturer of the cartridge.
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. Theoretically, a larger caliber should cause slightly more ...
WASHINGTON — President Joe Biden is preparing to face a few different Donald Trumps on Thursday's debate stage: the more bombastic and “unhinged” one known for his grievance-filled, stem ...
Ballistics by the Inch (often called BBTI) was a project to test the performance characteristics of a variety of common handgun calibers/cartridges. The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length.
