5.56mm Round (Fallout: New Vegas)

The 5.56mm round is a type of ammunition in Fallout: New Vegas.

Characteristics
5.56mm rounds are, generally, the general-purpose bullets for all Guns, spanning the entire game's arsenal, from the early varmint rifle to the light machine gun. 5.56 is common, light, and cheap, and is considered one of two 'small rifle' cartridges, the other being 5mm.

Creation
Standard 5.56mm rounds can be crafted at a reloading bench once the player has a Repair skill of 25. A single round requires the following ingredients:

Breakdown
Breaking down a 5.56mm round requires 25 Repair, and yields:

5.56mm, armor piercing
Armor-piercing rounds are designed for punching through armor plating, for this purpose they have a greatly strengthened case with a specially hardened and shaped nose. Due to the high muzzle velocity and penetrative properties of the round, damage to the target is slightly reduced. However they can be rather hard to find and vendors almost never have more than 200 in stock at any given time.

5.56mm, hollow point
Hollowpoint bullets mushroom and break up on impact, causing massive trauma on fleshy, un-armored targets. However, this also means they break up when they hit things like armor plate, drastically reducing the weapon's penetrating power.

5.56mm, surplus
Surplus ammunition is poor grade ammunition made in larger quantities by using corrosive materials in their construction. The resulting process is a slightly more damaging round but at the cost of more regular maintenance on a firearm due to the highly damaging corrosive materials used in the round's construction. This ammunition might also cost more than regular surplus ammunition.

5.56mm, match
New ammunition added with the DLC, Gun Runners' Arsenal. Match ammunition is precision-made so that every bullet has the same powder, shape, and weight. Match ammunition is often used in tournaments, sight alignment, and sniping. This ammunition type is gives a slight damage boost and a significant reduction in the weapons spread.

.223 round
A common commercial hunting round designed for Civilian use, most commonly used in hunting small to mid-sized game. This ammunition does less damage due to lower internal pressure, resulting in less stopping power. These rounds tend to put less stress on the chamber, resulting in better weapon durability. .223 ammunition can be bought in bulk from vendors. Prior to patch 1.3.0.452, these rounds had a -8 DT effect.
