Yesterday I acquired a couple of .303 inch rounds that I have been after for a long time.
The first was an aluminium cased Ball Mark VI that is thought to have been made by the British Aluminium Co. in WWI. I have had the Mark VII version of this for a long time but needed the round nosed Mark VI type.
The second was even better. It is a Smoke Discharger E Mark IT used to fire smoke grenades from Armoured vehicles. Approved in 1936 it was only used for a year or so before being replaced by the ordinary rifle Discharger H Mark I cartridge.
It is one of the rarest of all the .303 inch cartridges and the first I have seen in fifty years of collecting.
