303 British with dots around the VII headstamp


What is a meaning of the dots before and after headstamp VII?
Cartridge has bullet with GMCS envelope


Greenwood & Batley used various extrusion methods for making their cases and you will find them with many different patterns of dots in the headstamp. It might be an indication of the machine line used but AFAIK, it has never definitely been confirmed what the dots mean.

One could make a complete collection out of all the “dot” variations in GB headstamps.



Thank you very much for this information!
