Is it legal to make your own black powder in MD? Seems the rules states powders must be stored in their original containers so that would put you in breach if you made your own, right?
Having made my own when getting chemicals was less restrictive, I can tell you that it is a pain in the ass.
To be safe, you need to make small quantities which by itself is a pain.
While it does work, getting consistent results is impossible, at least when I did it. Today I imagine you can buy a tool to check the moisture level but separating the cake into similar size grains is impossible for a make it at home person.
Good luck if you try it.
Making your own BP is nuts and very unstable.
BP isn't unstable, it's sensitive. Important distinction. Unstable means it can degrade/react/etc. on its own probabilistically. BP is sensitive, in that it has a low (or at least lower than smokeless) threshold for environmental insults such as heat, friction, sparks, initiating a reaction when stimulated. But it doesn't go off on its own without some externally-provided initiation energy.
Actually, all propellants degrade over time and have a probability of autoignition. This is well documented and is the reason that the military and manufacturers do propellant stability tests. The older the powder the more likely a chance of degradation and autoignition. Storage conditions obviously play heavily into how fast propellant degrades. Black powder is listed as a high explosive (hazard class 1.1 as opposed to smokeless powder being hazard class 1.4). Modern black powder is coated with graphite in order to make it less sensitive but its is still capable of generating it's own static electricity if poured incorrectly. Black powder can be especially sensitive after exposure to moisture and humidity and then allowed to dry out. Making your own black powder is definitely not advisable unless you have the proper background and a facility to do it in.BP isn't unstable, it's sensitive. Important distinction.
