I have just this picture about the PBM ammunition
Someone can tell me if the headstamp are specially ?
do you have a better picture?

Nothing special in head stamps should be. Case is same and produced on same plants. The difference is only in bullet design and propellant weight (increased pressure).

One of the head stamps is “38 88”. These rounds are far from being new.
