Commercially, reduced-power .277 Fury Elite ball FMJ ammunition using non-hybrid conventional cartridge cases is offered, that fires a 135 grains (8.7 g) projectile with a G1 ballistic coefficient of ≈ .475 at a muzzle velocity of 2,750 feet per second (838 m/s) from a 16-inch (406 mm) barrel.
These ballistic tables were published in 1909 and almost identical to those of Ingalls. In 1971 the Sierra Bullet company calculated their ballistic tables to 9 restricted zones but only within 4,400 ft/s (1,341 m/s). [29] [9] [41]
Sierra still remains at that location, where they manufacture over 175 different bullets (as of Jan. 1, 2014) for their green box sales and several proprietary bullets for other companies. They employ about 160 people with 5 full-time Ballistic Technicians answering reloading and firearms questions on a daily basis. The company also employs ...
The .375 SOCOM is a fairly new cartridge, designed by Tromix in 2013. Taking a .458 SOCOM cartridge case and sizing the neck down to .375 caliber, resulted in a hard hitting AR-15 compatible cartridge, that has a considerable velocity and range advantage over the .458 SOCOM as well as other big bore AR-15 cartridges.
338 Edge (.338/300 Ultra Mag, .338 Ultra Cat) is a Wildcat rifle cartridge based on the .300 Remington Ultra Magnum round necked up to accept 0.338" diameter bullets. [1] It is gaining popularity as a long-range cartridge due to the wide availability of 0.338" projectiles that have a high ballistic coefficient.
The specification included a Remington-designed bullet and the use of IMR4475 powder, which resulted in a muzzle velocity of 3,250 ft/s and a chamber pressure of 52,000 psi. [ 8 ] In the spring of 1962, Remington submitted the specifications of the .223 Remington to the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI).
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
Here is an example of a ballistic table for a .30 calibre Speer 169 grain (11 g) pointed boat tail match bullet, with a BC of 0.480. It assumes sights 1.5 inches (38 mm) above the bore line, and sights adjusted to result in point of aim and point of impact matching 200 yards (183 m) and 300 yards (274 m) respectively.
