The evening your Level 2 bench goes down, this is one of the cheapest blueprints on it. Against a handmade shell the craft doubles the gun powder and swaps stones for metal fragments, so a full stack now costs 640 sulfur. What you buy with it is damage, and in a doorway that matters more than sulfur.
Learn slugs on the same trip. They cost the same scrap, use the same recipe to the last fragment, and all that is left to decide afterwards is which one to load.
Waste is never the issue here, since every craft takes exactly one batch of powder. Volume is. A pump shotgun empties a stack faster than you think, so keep powder crafted ahead and let the shells queue while you sort loot. Skip the incendiary shell unless you have sulfur to burn: it adds raw sulfur and doubles the bill again.
