Yes it is a hard grain black powder. I have to admit when I say we make them, that means I go to my buddies house with beer, we use all his toolings and chemicals and we make them there, and usually a shitload. I understand the principles of packing the delay charge and ejection charge etc...but his tools make them Pro.
The only modification we have to do is on the rockets themselves is to change the motor mounts.
Here is a good site that explains.
