PRIMA-FACIE EVIDENCE – evidence which,
standing alone unexplained or contradicted is
sufficient to maintain the proposition affirmed. It is
such as, in the judgment of law, is sufficient to
establish the facts, and if not rebutted, it remains
sufficient for that purpose.

PRIMARY EVIDENCE - that which the law regards as
affording the greatest certainty.

PRIMARY EXPLOSIVE OR INITIATORS – explode
or donate when they are heated or subjected to
shock. The materials themselves explode and the
explosion results whether they are confined or not.
Examples are Mercury fulminate, lead azide.

PRIMER – the metal cap containing the highly
sensitive priming mixture of chemical compound
which when hit or struck by firing pin would ignite.
Such action is percussion.

PRIMER POCKET – a hole on the base of the
cartridge case that holds the primer securely.
Performs triple functions holding primer securely in
central position providing a means to prevent the
escape of gas to the rear of the cartridge; and
providing a solid support of primer anvils, without
which the later could not be fired.

PRIMING – a metallic cup charge with a priming
composition. A blow from the hammer or plunger
striking the primer ignites the powder charge.

PRINCIPAL – the one who actually commits a crime.
