What is “HS” brass from American Reloading?

[Radom Guy]

I’m interested in buying some primed brass from American Reloading. I’ve bought demilitarized bullets from them in the past with good results.

In many of their listings, they state that the brass cases for sale are “HS” brass. Does anyone know what the heck that means?

I figured I would get a quicker answer to that question by asking here vs. sending them an email. Thanks in advance.

HS = headstamp

Mixed headstamped brass.

Yes, of course, thank you! I don’t know why I did not see or get that without asking, haha!
Thanks again.

I was thinking HS meant highly shined, but that seemed silly.
