With Catalyst, that would certainly be nitrocellulose, which makes up about 20 percent of the guide compound. The aluminum also reacts with bismuth oxide (60 percent of the primer)yep, that's the very same bismuth in safe shot with a thickness similar to leadto create what Federal engineer Sandstrom calls a "thermite reaction," which is an expensive method of stating that the light weight aluminum obtains the bismuth really, really hot.

In very early black powder guns such as muzzleloaders, the primer was essentially the exact same chemical as the major propellant (albeit typically in a finer-powdered kind), Source yet put right into an outside flash pan, where it might be fired up by an ignition resource such as a sluggish suit or a flintlock though some muzzleloaders have guides like cap weapon caps.

As gunpowder will not burn when damp, this made it tough (or perhaps impossible) to terminate these sorts of weapons in rainy or moist problems.
