Head Stamps

What is a Blank Head Stamp?

The Blank Head Stamp is the identifying marker on the bottom, or end of a case where the primer is.  For many of our blanks we have our own custom blank head stamp made.

Here are a few examples of such blank head stamps.


Our Plastic blanks have a headstamp that say “MRA”
