If I could post this question here, since there has been some references to bluing, what is "straw bluing, assuming I have the term correct? In the back of my mind I have the notion that it's something used only for small parts, especially on automatics. And also, when restoring old firearms, what is the best thing to do with case hardened parts, which I suspect, often as not, nothing may even be necessary.
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
