The 4TH kept all that and has economic, resources rules centered around X amount of labor and materials for Y item at tech level Blank. economics center on the requirements for a kg of black or smokeless powder. I'm not doing the rules justice. Considering for 3RD ed. I was scrounging small industry, high school science and shop teachers for machinery and most ammo cases, bullets.

The people the team will encounter use black powder rifles for hunting because it's cheap and have M1911's under their jackets. BTW I forgot 230gr ball in the list. Perhaps the commercial M1911 load I read about
