If you would like...
to have less mechanical details try watching 'Sharpe's Eagle', a TV drama now on DVD, based on one of Bernard Cornwall's books about a soldier who makes his way through the ranks to officer, thanks to Wellington and the Napoleonic Wars. (19thC) There's a good passage where he is instructing the new soldiers on how to use their muskets.
You need to see how a musket works to understand the noise, the smoke, the powder on your face and up your nose, your dry mouth from ripping open each cartridge with your teeth to get the powder for the pan and the bullet to force down the muzzle with those awkward ramrods.
If you can get to a 'black powder' group (I think you call them that in the US) there will be some kind enthusiast only too happy to demonstrate or even let you have a go. It's amazing to see a group firing and see the smoke like thick fog, and smell that smell!
