| Most Primer
Compound, for caps, bullets, and shotshells, are made using Lead
Styphnate; otherwise known as 2,4,6, Trinitroresorcinate which is made
from Styphnic Acid. Because it is a Lead based material, it is being
phased out. Diazodinitrophenol (DDNP) is another compound - more
suitable. In my search for a safer Primer Compound, I found a mixture
that uses Potasiumchlorate, Antimony Sulfide, and Sulphur. I also found
a mixture that is the same, except it does not use Sulphur.
Unfortunately, I have not found a recipe for this mixture. Oh by the
way, In my searches, I discovered that one needs a License to purchase
Primer Compound, and a License to sell Primer Compound, and a License to
Manufacture for commercial selling. There are no laws prohibiting making
your own, that I have found, but there are restrictions of some of the
ingredients. So for restricted ingredients, you will have to make them
yourself. If you are in a pinch, and need to reload your existing
primers, it can be accomplished. There are videos on youtube.com that
show how to use the material on match heads for that, and also how to
use cap pistol "caps". They are shown to actually work. |
Diazodinitrophenol (DDNP) is a yellowish brown powder. It
is soluble in acetic acid, acetone, concentrated hydrochloric acid, and
most non-polar solvents but is insoluble in water.
