All you have to do is measure the amount of gunpowder and pour it into the empty shells. Melt down the lead and pour it into moulds and but it in a press. Add the primer to the bottom and you're good to go. Tons of people who shoot reload their shells to save money on new ones.

On the topic of punishments for crimes within a community, maybe a way to make a permanent mark on someone. A brand or something or make them wear a certain type of clothing. Forever in the community they will be labeled a thief. I like the idea of imprisoning players though, tons of potential and unpredictable outcomes.

I think it would be cool if given the proper equipment we could craft ammo. Something like collecting used shells or finding them randomly then finding gunpowder and maybe a chunk of lead. I've seen it in person and its fairly simple to do. I think it would be especially fun in multiplayer stocking up and having a small army of well equipped friends as long as it is quite time consuming to gather all the resources to do so.
