O ratio is also used to predict barrel life in cartridges of the same caliber, but not of different calibres, since the ratio is an extensive quantity that does not correlate to temperature or pressure (e.g. a .50 cal straight cartridge may have the same overbore as a highly necked down .17 cal cartridge).
The cartridge was originally designed as a deer stalking round with a 260 gr (17 g) bullet, although later a 530 gr (34 g) loading was produced for target shooting. [1] [2] The .500/450 No. 1 Nitro for Black was the same cartridge loaded with mild loadings of cordite, carefully balanced to replicate the ballistics of the black powder version.
The 3-inch and 3 1 ⁄ 4-inch .500 BPE cartridges have survived to the current day as the .500 3-inch Nitro for Black and the .500 3 1 ⁄ 4-inch Nitro for Black, the same cartridges loaded with mild loadings of modern smokeless powder, carefully balanced through trial to replicate the ballistics of the Black powder version.

In African rifles and cartridges Taylor compares the effect of a near miss of an elephant's brain from a frontal head shot with the .416 Rigby and the .470 Nitro Express, two cartridges with similar muzzle energy but different bullet weights. Taylor states that the .416 Rigby will probably not knock the elephant out, but momentarily stun the ...
The propulsion system uses an obturating case base with a semi-combustible cartridge wall. It has a total weight of 41.1 lb (18.6 kg) and a 627 mm (24.7 in) DU penetrator with a 27 mm (1.1 in) rod diameter, [ 2 ] which reaches a muzzle velocity of 1,670 meters per second (5,500 ft/s) using 8.1 kg (18 lb) of JA-2 propellant.
A comparison table below that details the NIOSH protection designations, 42 CFR 84, the Navy/Marine Field Manual, [26] the NIOSH TB guide, [19] and whether they match up with the (42 CFR 84-declared ANSI K13.1-1973 revision) ANSI Z88.7-2001 colors, for each type of chemical cartridge is described below.
