8x50R Lebel and 7,5x54 MAS - 2 in 1


I have this strange cartridge with plastic body in cal. 7,5x54 MAS and brass base of 8x50R Lebel.
Have no idea what is it and for what purpose and when it was made.
Could somebody help me with info regarding this strange cartridge?
Thanks for any info


this cartridge is made for blank firing with bolt action guns in 8x50R lebels for movies (cost less than news 8x50r blanks)


Thank you very much!


These were made by famous Alexandre Règie-Films company from Paris. Wooden blanks were also used.


Thank you, Fede!
