The traditional method of carrying gunpowder is to use a powder horn, & in my opinion this is still the best method. The base plug in a powder horn should NEVER be glued to secure it in the horn. This base plug is a safety release should the horn explode. The base plug blows out & releases the pressure. This base plug is sealed with beeswax only, & secured with only 4-6 metal or wooden pins. For carrying extra gunpowder I use a greased leather gunpowder wallet or gunpowder bag. The use of a gunpowder bag is traditional, & if a bag becomes empty, it is used to store plant or fungi tinders. This is one of five gunpowder bags that I have made for carrying extra supplies in my knapsack for long term wilderness living. Keith.
