Chapter 2 of the police guide:
2.9 Ammunition means ammunition for
any firearm and includes grenades, bombs
and other like missiles whether capable of
use with a firearm or not, and also includes
prohibited ammunition. It will be noted
that the definition of ammunition does
not include ingredients and components
of ammunition; it is only assembled
ammunition that is controlled under the
Act, not component parts. Empty cartridge
cases, for example, are not ammunition.
The only exception to this is the missiles for
ammunition prohibited under section 5 of the
1968 Act, for example expanding or armourpiercing
bullets. Such missiles are themselves
regarded as ammunition and are subject to
control accordingly.
