Hi all.
Very new here but have a question that has come to light.
I have an aquire and keep license for black powder (un0027. un0028). plus all the RCA docs etc.

I store the powder in the appropriate box as requested by the police and in my home which the police have inspected and are happy with.

I have not however any official documentation that states in black and white the quantity of powder i can store at my premises. Does anyone know of such a document and where i can get my hands on it.

I dont really what to ask my powder officer just yet as it doesnt really instill confidence.

Thanks for any hep in this matter
Regards
Spud
