Monolithic bullets have been used for hunting big game in the USA for decades. The first popular all-copper bullet was the Barnes X bullet in 1986. [7] Since then, most bullet companies have a monolithic bullet on the market, including Nosler E-tips, Hornady GMX, Barnes TTSX, LRX, VOR-TX, Federal Trophy Copper, Winchester Powercore 95/5, Hammer bullets, Cutting Edge Bullets, Lehigh Defense, G9 ...
The .243 produces a velocity of 3,200 feet (980 m) per second from factory-loaded expanding monolithic copper projectiles weighing 85 grains (5.5 g) fired from a 24-inch (610 mm) barrel. [28] Other variations of commercially loaded .243 ammunition are available with bullet weights ranging from 55 grains (3.6 g) up to 115 grains (6.8 g).
The .458 SOCOM (11.63×40mmRB) is a moderately large round designed to work in an AR-15 platform.This is achieved by installing a 458 bolt and barrel. The 300-grain (19 g) round offers a supersonic muzzle velocity of 1,900 ft/s (580 m/s) and 2,405 ft⋅lbf (3,261 J), [1] similar to a light .45-70 but with a much smaller case.
The minimum cartridges for hunting of dangerous game was set at either the .375 H&H Magnum or at the 40 caliber (10 mm) with a few countries allowing the 9.3 x 62 Mauser as an exception to the rule. Remington realizing the opportunity designed what was to become the second dangerous game cartridge to originate in the United States to be ...
Due to the necessity of seating heavier longer bullets more deeply into the powder column due to the short design and maximum overall length of the .325 WSM cartridge, velocity drops off as bullet weight increases. This is particularly evident with mono-metal bullets such as Nosler's E-Tip bullets, and the Barnes X bullets.
The 6.8mm Remington Special Purpose Cartridge (6.8 SPC, 6.8 SPC II or 6.8×43mm) is a rimless bottlenecked intermediate rifle cartridge that was developed by Remington Arms in collaboration with members of the U.S. Army Marksmanship Unit and United States Special Operations Command [6] to possibly replace the 5.56 NATO cartridge in short barreled rifles (SBR) and carbines.
The .257 Weatherby is known for its long range performance and is considered an accurate flat shooting cartridge. Initially due to the cartridge's high velocity the cartridge exhibits less bullet drop than most other cartridges. However, due to lower ballistic coefficients of these bullets, velocity (and therefore energy) is shed more quickly.
A key simplifying assumption Gurney made was that there is a linear velocity gradient in the explosive detonation product gases; in situations where this is strongly violated, such as implosions, the accuracy of the equations is low.
