.297/250 Rook

The .297/250 Rook 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.

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. This cartridge is a contemporary of the .255 Jeffery Rook and upon their release the pair competed heavily with the very popular .300 Rook.

As with other rook rifle cartridges, the .297/250 Rook was superseded by the .22 Long Rifle.
