It was used for pistol and submachine gun ammunition and held 2,000 rounds in cartons (100 x 20-round cartons or 40 x 50-round cartons). It could also be used to hold 960 rounds of Caliber .30 ammo (48 x 20-round cartons) or 240 rounds of Caliber .50 (24 x 10-round cartons) ammo. Another box (Volume: 0.83 cubic feet) was used for carbine ...
P: Momentum, in pound (force) (lbf) times seconds. [1] A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.
Winchester initially added a rim to the cartridge because the company wanted to use the cartridge in an anti-tank rifle, but Pershing insisted the cartridge be rimless. [20] The first .50-caliber machine gun underwent trials on 15 October 1918. It fired at less than 500 rounds per minute, and the muzzle velocity was only 2,300 ft/s (700 m/s).
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.
The International Confederation of Fullbore Rifle Associations (ICFRA) is the international association for the fullbore rifle shooting sports of target rifle ('TR') (called 'Palma' rifle in the US) and F-Class, which are long range competitions shot at distances between 300 and 900 meters or 300 to 1,000 yards depending on the range.

The 6.5-284 has been used extensively in benchrest competitions and is known as an extremely accurate long range round. Using an improved version of the 6.5-284, Rich DeSimone set a 1,000-yard (914.4 m) world record with a 1.564-inch (39.73 mm) group. [4]
500 S&W Magnum hunting load with 500 gr. SP bullet by Hornady. The .500 S&W Magnum was originally designed to be primarily a handgun hunting cartridge. It also serves a secondary purpose as a back-up survival handgun cartridge as a defense against the large bears of North America. [16] Size comparison of a 500 S&W round and a human hand
The cartridge is capable of producing over 5,400 J (4,000 ft⋅lbf) of energy at a range of 100 m (110 yd). In comparison, the typical .458 Winchester Magnum firing a 32 g (500 gr) bullet at 620 m/s (2,050 ft/s) manages to stay above the 5,400 J (4,000 ft⋅lbf) just past the 46 m (50 yd) mark.
