.357 Magnum Round

.357 magnum round is a type of ammunition in Fallout: New Vegas.

Characteristics
A .357 caliber bullet, with a significant powder charge. Very powerful for a pistol round.

Variants
.357 Hollow Point -- Hollowpoint bullets break up on impact, tearing through fabric, flesh and organs with ease. However, hollowpoints lack the penetrating power to punch through denser materials, like leather and metal. Best used against lightly-armored or unarmored foes.
 * Gun Damage -- x1.75
 * Target DT -- x3.00

.357 JFP (Hand Load) -- JFPs (Jacketed Flat-points) are blunt, copper-wrapped bullets designed to flatten on impact like a hollowpoint, but retain the penetrating power of a copper-jacket slug. As such, they inflict greater damage, penetrate enemy armor better, and even fly straighter than normal .357 rounds.
 * Gun Damage - x1.25
 * Target DT - -3.00
 * Weapon Spread - x0.80

.38 Special -- .38 Specials are a slightly smaller class of bullet in comparison to .357 magnums. They can be fired from .357 weapons because the .357 Magnum was developed from the .38 Special round. Though the reduction in powder means less damage inflicted on your targets, it also means more wear and tear on the gun that fired it.

"More wear and tear" comes from the need to fire more bullets to kill a target, each individual bullet actually does less damage to the weapon firing it than normal bullets.
 * Gun Damage - x0.75
 * Weapon Condition - x0.75
