I would like a pic too of the headstamp. As Dave has shown, Blazer is available in brass now and is reloadable.
I don't condone it, but in a survival scenario, is possible. I have an friend that has a Mac 10, legal full auto, in .45 acp, and he has been reloading Blazer aluminum for years, He uses Lee dies and when resizing, just punches a third flash hole right through the center, as Blazer is berdan primed. This is for information only, I have not done it and would only do so for experimentation, with a firearm I did not care that much about, for future use.
