The .380 Long [9.8 x 24mmR], also known as the .380 Rook rifle, is an obsolete centerfire rifle cartridge.
The .380 Long is a straight rimmed cartridge originally designed for use in rook rifles for target shooting and hunting game up to the size of smaller deer.[2] In addition to British munitions makers, the .380 Long was also made by DWM in Germany and a number of cheap European pistols were chambered in it.[1] This cartridge is very similar to the .38 Long Colt and may have inspired the latter cartridge's development.[2] As with other rook rifle cartridges, the .380 Long was superseded as a small game hunting and target cartridge by the .22 Long Rifle.[3] As a pistol cartridge, the .380 Long gradually lost favour to more modern rounds such as the .38 S&W.[2]
