12.7mm Round

12.7mm rounds are a rare type of ammunition manufactured by Hauer Premium in Fallout: New Vegas.

Characteristics
The Hauer Premium Show Stopper 12.7mm civic defense round is a large pistol round.

Production
Standard and JHP 12.7mm rounds can be crafted at a reloading bench. A single cartridge requires the following ingredients:

Breakdown
Breaking down a standard 12.7mm round yields:

Weapons using this ammunition

 * 12.7mm pistol
 * Li'l Devil
 * 12.7mm submachine gun
 * 12.7mm submachine gun (GRA)
 * Survivalist's rifle

12.7mm round, hollow point
Hollow point bullets mushroom and break up on impact, causing massive trauma on fleshy, unarmored targets. However, this also means they break up when they hit things like armor plate, drastically reducing the weapon's penetrating power.

12.7mm round (junk)
The Junk Rounds perk from the Dead Money add-on was at one point intended to create ammunition of a special subtype. Called "Junk" or "JNK", these rounds all provided the same modifiers regardless of caliber: 0.75x to Damage and 1.5x to Gun Condition. The rounds remain present in game code but are not placed in any locations, and if somehow obtained cannot be used in any weapons, even those chambered for the correct caliber.

Curiously, the presence of 12.7mm JNK rounds indicates that the perk was to provide a recipe for crafting 12.7mm rounds, though the final version of the perk does not include one. This may be a bug or oversight, similar to 12.7mm ammunition's initial absence from most merchant inventories and the lack of a crafting recipe for the ammunition.

12.7mm round, JHP hand load
A new type of ammunition added with the add-on Gun Runners' Arsenal, JHP, or jacketed hollow point, uses a metal-clad bullet that retains most of the damage bonus of ordinary hollow point rounds, but with a less severe armor penalty.
