The .360 No. 5 Rook is an obsolete centerfire rifle cartridge.
The .360 No. 5 Rook is a straight rimmed cartridge originally designed for hunting small game and target shooting in rook rifles, although it was also used as a pistol cartridge.[1] The .360 No. 5 Rook was introduced between 1875 and 1880 by lengthening the older .380 Long cartridge.[2] This cartridge was initially available in both 134gr rifle loadings and 125gr pistol loadings, both cartridges being interchangeable.[2] Shot and blank cartridges were also available.[1] As with other rook rifle cartridges, the .360 No. 5 Rook was superseded as a small game hunting and target cartridge by the .22 Long Rifle.[3]
