In terms of the Regulations of the Explosives Act, 1956, Act 26 of 1956 (as amended), and as published in Government Notice R1604 (dd 1985-10-25), the following is stipulated in Regulation 8.23.1 and 8.23.2 re propellant a firearm licence holder may have in his/her possession for purposes of reloading of own ammunition:

8.23.1 Notwithstanding anything to the contrary contained in these regulations, persons who are in possession of one or more valid firearm licences issued in terms of the Arms and Ammunition Act, 1969 (Act 75 of 1969)*, may in respect of each such licence keep on their premises 600 grams of nitrocellulose propellants for the private reloading of cartridges of small arms only and not for sale or other trade: Provided that the total amount of nitrocellulose propellants so kept shall not at any time exceed 2 400 grams in mass.

8.23.2 The nitrocellulose propellants shall be kept locked up in a sturdy cupboard (however, SAPS have recently indicated that they prefer propellant to be kept in a safe).

* The Arms & Ammunition Act, 1969 (Act 75 of 1969) has been replaced by the Firearms Control Act, 2000 (Act 60 of 2000 as amended - also known as the FCA).
