Just been emailed the above link from my club chairman, pass it on. His thoughts were -

Ask yourself why you can hold 10 Kg of Black powder but only 5 Kg of Nitro powder, why not a mix of either type up to a combined limit of 15 Kg

Why do you need an RCA document as well as an explosives licence,

why do you need a separate explosives licence when you have a firearms licence the police issue both?

Pass it on & respond please !
