All the stuff I've seen here has been '70s and '80s manufacture, with 1969 the oldest. It was about the best surplus stuff on the market at that point.
Still have thousands of the cases, will last me for many years.
A large quantity was procured in the 1980s for the various schools & cadets corps, who still used .303 rifles and emmagees at that time.
Some batches had WW2 ball and tracer rounds packed in randomly.
