Fallout: New Vegas Crafting

Basics
Crafting is used for building a large range of things. Crafting covers creating custom ammunition with the use of the Repair skill (e.g. .308 JSP and .44 Magnum Semi Wadcutters), creating custom weapons using the Science skill, and through the Survival skill for cooking food and making medicinal items.

One of the reloading bench's primary purposes is to convert different forms of ammunition to others, making otherwise useless ammo immediately valuable.

The main ammo conversions (reversible) are:
