I recently acquired this .303 cartridge with nothing but two separate characters “R 7” as the headstamp.
The cartridge had been inerted when I bought it, so I cannot give any details on the propellant.
Everything about the cartridge is classic British made .303. The bullet is marked with an eight pointed star in the lead base. I know that this is a known makers mark, although I cannot recall who used it.
Does anyone here know anything more about this cartridge?
Thanks for any information.
