the invention of a gun that combusted with black powder to shoot the bullet
That will all depend on your gun, and the powder. There are as many opinions as there are powders. I have guns that will only shoot true black powder, and a few that shoot synthetic better that true black. The newer "in-line" guns are designed to use synthetic and do tend to shoot it well. the older style side lock and flintlocks tend to do better with true BP. If you are looking for accuracy the bottom line is what your gun - bullet combo likes best. Take some time at the range and shoot some 5 round groups with both and you will have your answer. As for what powder to use, the synthetics are all very similar to each other ( check the label) I use Goex Pinnacle only for the reason I order it with my true BP. Good luck, have fun!
Possibly. 1918 was well into the smokeless powder period. Have it checked by a gunsmith first.
