.45 Auto, +P
.45 Auto, +P (Over-pressure) is an ammunition designed to fire at a higher internal pressure than standard ammunition to ensure higher velocity, stopping power and a slight armor piercing ability but at the cost of requiring more maintenance than usual. This ammunition can be bought at most vendors in small quantities. It can also be made at a reloading bench.

+P rounds can be crafted once the player has a Repair skill of 45. A single round requires the following ingredients:
 * 1 case, .45 Auto
 * 17 lead
 * 10 powder, pistol
 * 1 primer, large pistol

.45 Auto, hollow point
.45 Auto, hollow points is an ammunition manufactured by Federal Cartridge corporation and designed to 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 plating, drastically reducing the weapon's penetrating power.

.45 super (hand load)
.45 super is an ammunition load manufactured by Southern Cartridge company and designed for much higher pressures than the gun was originally intended to fire. Muzzle velocity is 20% greater than even +P resulting in much better armor penetration and damage, but causing considerable weapon damage to guns not specially designed to operate these "Wildcat" rounds. You must take the perk 'Hand Loader' to be able to craft this round at a reloading bench.

Components
.45 super rounds can be crafted once the player has a Repair skill of 80, as well as the Hand Loader perk. A single round requires the following ingredients:
 * 1 case, .45 Auto
 * 19 lead
 * 12 powder, pistol
 * 1 primer, large pistol
