really weird chambers

Hi,

The normal shape of the 9mm cartridge is a slightly tapered one. For a decent fitting, the chamber therefore should also be tapered.

It proved to be easier/cheaper/quicker those days to create a chamber with a stepped straight-edge design. This ensures correct chambering and produces the ring mark as a result.

Good quality cases will only show scuff marks, thin-walled cases will actually show a bulge.
