Summary

The .320 Revolver (AKA: .320 European, .320 Bulldog, .320 Webley) is a Center Fire cartridge with a Bullet Diameter of 0.317 in” (8.05mm) that is primarily used in Pistols. The .320 Revolver originated in The United Kingdom in Approximately the 1870s. The .320 Revolver also has a case length of 0.62 in” (15.75mm) and an overall length of 0.9 in” (22.86mm).

Notes

The .320 Revolver was developed in the late 19th century in England as a black powder cartridge for use in the Webley Revolver, also known as the British Bull Dog Revolver (when chambered in . 455 calibers), a civilian version of the Royal Irish Constabulary Revolver M1883, designed by Philip Webley & Son. The .320 Revolver is most notably known for being the inspiration for the .32 Short Colt, a nearly identical American made cartridge with a larger Rim Diameter. Although .32 Short Colt ammunition can be fired from a .320 Revolver firearm, only the original black powder loads should be used, as firing a modern .32 Short Colt with a Smokeless Powder Load would be highly dangerous.

Power in terms of velocity and muzzle energy for the .320 Revolver are somewhat miniscule, not unlike the .32 Short Colt and .32 Long Colt Cartridge. For velocity, you could expect about 500fps give or take with muzzle energies being below 100 ft-lbs with an 80 grain projectile. While the .320 Revolver may have had loadings up to or around the same energy levels as the .32 Short Colt, most historical data seems to indicate the .32 Short Colt as being nominally more powerful than the factory loadings for the .320 Revolver Cartridge.
