Fallout: New Vegas Crafting

Basics
Crafting is used for building a large range of things, which means misc. items have a lot more practical value than in Fallout 3. 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. However, these conversions do not share the same hulls needed, sharing only lead, powder, and primer, so these are not a straight conversion.

The main ammo conversions (reversible) are:
 * 5mm with 5.56mm
 * 12 Gauge- with 20 gauge shotgun shell
 * 10mm with .44 Magnum
 * .308 with .45-70 Gov't
 * 9mm with .357
