Smokeless propellant isn’t difficult to make.
Making a particular burning rate of smokeless propellant.... well, that takes some work.
But making something like gun cotton and then molding it - not that difficult.
It all seems like a huge problem to people who are liberal arts majors, who know nothing about manufacturing or machining... but there are enough of us out here who read poetry only as a hobby because we knew it would never pencil out a family budget. The barrier to making one’s own powder and primers is not as high as some would believe.
ok
