The 300 (295) Rook was introduced in England in the 1870's, as a small game,
black powder cartridge for the single shot rifle.
It was also made in the U.S.A. by at least Remington.
It became obsolete in the early 1960's, after Eley-Kynock dropped it from production.
Two different Headstamps available below.
