Not spontaneously, but it sure will do that if ignited with a blasting cap.

True indeed. Smokeless powder is more sensitive to a pressure shock than
dynamite or, for example tetryl or PETN. Tetryl and PETN are about the
most sensitive explosives used in practice, btw. Pistol and shotgun powders
are particularly sensitive, about twice as sensitive as tetryl.
