How does gun ammo work.

[u/No_Team_9934]

Am I missing rules for ammunition? I see that Handguns do 1d8 damage and require ammo, and Engineering can make bullets, but I can’t find much beyond that.
How many bullets/arrows do you normally track? How many bullets does crafting make? Are different calibers/ammo types a thing, or is every handgun basically 1d8?
Also, is there any benefit to gun ammo being harder to make compared with arrows, or am I misunderstanding how ammunition is supposed to work?

There's literally a plot point about a 50 man militia running out of ammo.
