.410 inch Indian Musket Ball, Blank & Buckshot
The memory of the Indian Mutiny lingered long in the minds of the British and so they ensured that the large native militia and police units were always armed with weapons inferior to those of the Indian and British armies yet were effective enough to do their job.
For many years these units had been armed with smooth bore versions of British weapons and this continued with the introduction of the .410 Indian Musket in the 1920s. These were SMLE rifles smooth bored to .410 inch calibre and converted to single shot./
