Here’s an interesting box of .303 British cartridges that had their full metal jacketed bullets replaced with soft point bullets in Finland for Interarms. There is no ‘keep out of reach of children’ warning on the box and the Interarms address does not include a zip code so this box was probably sold by Interarmco prior to 1962. Most of the cartridges are headstamped R^L 1939 VII. I suspect the box held 7.62 Russian cartridges originally.
