SHTF normally focuses on short-term survival situations where after a prepper is done getting over the initial shock, it's only hours or days before the situation is over.
However, not all SHTF situations will be temporary. How can you know for certain that when the grid goes down that it won't be permanent? It's hard to know for certain; a natural disaster could wipe out everything except for the people who lived through it because they have durable bunkers.
The possibility of a long-term SHTF situation is why people think it's vital to understand and know the skills on how to make necessary items such as weapons and more specifically, gunpowder.
If survivalists are smart, they will already be working hard at stockpiling food that'll last them months or more. However, when it's all gone, they will need weapons to help catch food. And when ammunition disappears as well it'll be important to have the skill of knowing how to make more of it.
After the break, you'll be glad you took the time to learn step-by-step instructions on how to make gunpowder for a long-term SHTF situation.
Adding this essential skill to your survival expertise is something you shouldn't pass up!
