I also found a 9mm with the headstamp W R A 9mm, what does the WRA mean?
With or these bullets were found in South Australia

MF = SAAF Footscray, Melbourne, Australia and you have a 7.62x51mm round manufactured in 1958. L2A2 is the designation for the load itself. In this case, it is a ball round.

WRA = Winchester Repeating Arms.
