Wow, interesting information on the 9mm. Did not know that.
While I have someone whose interested in south Australian ammunition I may aswell share some of my other interesting finds.
I was advised to look at an old gun range on the coast of South Australia (port Macdonnell to be specific) and have found a wide range of unique shells and bullets (and many other bits and pieces) most of the gun ranges stuff is dated anywhere between the late 40s to the early 60s.
So here’s a picture of my collection of bullets I have found.
There are also still a few shells which I am unsure of, I believe the smaller ones are 27 caliber and the larger is 30. One of the smaller has the headstamp “SI” (which is a proud headstamp, but very light) but the other 2 blank. They are all rimfire. I will attack an individual pic below. Any idea or opinions are appreciated.
