The Mec magnum shot/powder bottle was designed specifically for storing your powder until you are ready to use it. It is unsafe to put powder in a glass jar or bottle or any other container which could cause pressure buildup. Store your powder where there is no chance of spark, fire or flame, where it is cool and dry and where children cannot reach it. Modern smokeless powders must be confined to cause an explosion.
