Fun fact for you. Modern firearms haven’t used black powder for a very long time, that’s why when people fire rifles you don’t see huge clouds of smoke
There are also many kinds of gunpowder, rifles use different powders to say shotguns or pistols. Although often times shotgun and pistol ammunition uses the same class of powder (slower burn rate iirc)
This feels like a lot of hoops to avoid reading a wiki page thoroughly But if you want to use gpt this may work
