In reality clause 2 (possession of components) has 3 conditions that must be met to be an offence.
The offence in clause 2 requires firstly, that the person committing the new offence has any of the components in their possession.
Second, that the person has the INTENT of manufacturing ammunition.
Third - and critically - that the person would have NO LAWFUL BASIS for having the ammunition once it was assembled and complete.
In that way, the clause ensures that those who are able to hold ammunition by virtue of a firearm certificate issued under section 1 or who are registered firearms dealers under the Act and permitted to possess or manufacture such ammunition, will not be caught by the new offence when going about their lawful activities.
Basically, individuals possessing components of ammunition that they use lawfully, for such purposes as reloading ammunition, which they are legally able to possess, are NOT COMMITTING ANY OFFENCE under the new legislation.
