If you are really curious, head to your local gunshop and ask the proprietor your question. Chances are he or she will open a package of primers and show you how they are constructed.

LOL I should have been clearer. Let me try again...
IF we HYPOTHETICALLY were to take apart an unfired round (realizing that doing so is EXTREMELY dangerous and should never be attempted), what would we see when looking at the primer?
Is this better?
Thanks.
