The .297/250 Rook / 6.4x21mmR is an obsolete centerfire rifle cartridge developed by Holland & Holland.
Overview
The .297/250 Rook is a bottlenecked rimmed cartridge originally designed for use in rook rifles for hunting small game and target shooting.[1]
This cartridge was introduced by Holland & Holland some time before 1880 by blowing out the neck of the .297/230 Morris Long to .250 in (6.4 mm).[3] This cartridge is a contemporary of the .255 Jeffery Rook and upon their release the pair competed heavily with the very popular .300 Rook.[4]
As with other rook rifle cartridges, the .297/250 Rook was superseded by the .22 Long Rifle.[5]
