The Ross rifle was a straight-pull bolt-action rifle invented by Charles Ross, a Scotsman, and produced in Canada from 1903 until the middle of the First World War. Although the Ross was a superior marksman's rifle, it had many faults in the adverse environment imposed by trench warfare, and after numerous complaints, the replacement of all Ross rifles in the three Canadian Divisions by the Lee-Enfield was ordered. Snipers, however retained a considerable fondness for the weapon.
