This Hungarian fellow who styles himself capandball on the Internet has a really thick accent but if you listen closely you can get the gist of his description of the 1861 Springfield rifle-musket he’s firing here.
I would only note that most Confederates, if not most Yankees, preferred the British Enfield Pattern 1853 to the Springfield any time they could scarf an orphaned Enfield up off the battlefield.
Pity he’s not shooting at night so you could watch the impressive 3-feet of flame the black powder produces out the Springfield’s business end. Something that ended when cordite, or so-called smokeless powder, was introduced in 1889. Cordite also made the “fog of war” metaphorical, whereas it had long been literal with the copious amounts of smoke produced by black powder.
