Hmmmm.......That is an odd statement. My Commercially Manufactured Black Powder storage magazine is made from steel, with an anti-static liner. The lid even has two locks on it.Originally Posted by Sindone
The real requirement here is that the storage container be "Explosion Proof". That simply means that the container will not trap the combustion of the powder, it will rip open before any serious pressure develops. Powders that are unconfined will not produce anything more than hot wave of flame and smoke.
