During the second world war, and several years afterwards, the UK bought USA produced .50 bmg (12.7x99) cartridges from the USA.
What types were used, and are only certain headstamps used for these contracts?
I know that also .30 caliber (.30-06) was sold to the U.K. and most of these rounds had the primer ringed in so they could be used in synchonised guns.
are these .50 bmg cartridges also marked in one way or an other? So can you identify them?
who can help with more info?
thanks in advance
