Yes, the manual hand-rammed methods in the Teleflite book could be rather involved. I was put off trying them by the first step given in the book, which was the construction of a steel plate "explosion shield."
Sugar rockets aren't quite as hazardous to make as black powder motors, and they lend themselves to core-burner grains. (It's really a necessity with sugar motors due to the propellant's lower specific impulse.)
