Buying or selling primers

It is an offence to buy or sell primers for metallic cartridges unless the seller or buyer;
- is a registered dealer
- sells by way of trade or business for primers or empty cartridge cases incorporating primers
- produces a certificate authorising them to own a firearm that relates to the purchase of a primer, including the ammunition for such a weapon
- is a duly authorised Crown servant
- shows they are entitled under an enactment to own a firearm or the ammunition of such a weapon without a certificate
- shows they have authority to purchase primers on behalf of another certificate holder
- is authorised by regulations to purchase primers. This is a contingency provision and to date no regulations have been made.
Storage and security of black powder
Anyone who stores explosives has a legal duty to keep them safe and secure. This includes;
- controlled explosives such as black powder
- non-certificate explosives such as ammunition, smokeless powder and primers.
The regulations allows small quantities of certain explosives, including black powder, to be stored without the location of storage being licensed, as long as the owner of such materials holds a valid explosives certificate for their own personal shooting purposes, such as muzzle-loading handguns and rifles.
Acquire only certificate
If you have an acquire only explosives certificate for the use of black powder, you must not store any black powder.
Acquire and keep certificate
If you have an acquire and keep explosives certificate for black powder, you may keep it without a registered store for example;
- up to 15kg black powder where only black powder is kept
- up to 10kg black powder with 5kg smokeless propellant
- up to 15kg of small arms ammunition or percussion caps, without the need for registration of licensing of the storage premises.
Correct powder storage
Powder storage is to be kept in its original container of plastic or cardboard up to a quantity of 1kg per container.
Containers can be stored within a partitioned wooden box, fitted with a hinged, airtight sealed lid, secured by hasp and padlock. Each partitioned section must have 30 percent additional height between the container top and the box lid.
The box must not be located near an entrance to property, near mains services or sources of ignition.
