There have been many sucessful reports of testing performed on non-regulated smokeless.
Ouch, that hurts coming from someone too scared to use their name. If BP is the only way you can think of for getting a parachute out of a cardboard cylinder, your creativity level is called into question.
You can certainly have BP. As I said, have a replica of an 18th century mortar made. Clearly an antique device.
