Fairly certain that the propellant bags the lads were loading were bog-standard US Navy 110-lb charge bags for the MkVII 16″/50 battleship guns from the Iowa-class BBs, which is what the HARP gun was built from. While the ignition patches at the base of each propellant bag are indeed black powder, the propellant is not. Otherwise, outstanding video; as both a former Canadian gunner and a former defence scientist, Gerald Bull’s tale has always been a cautionary one.@Pest789

I don’t know where you got the idea that the gun used black powder as a propellant, but all of the documentation I can find lists surplus naval propellant as the propellant used in the project. The US hasn’t used black powder as an artillery propellant since before 1900.
Edit: Your own animated graph lists M8M as the propellant, which is mostly nitrocellulose and nitroglycerin, not sulfur, carbon, and saltpeter
