The powerful .44 Magnum round was originally developed for revolvers. Soon adapted for pistols and even rifles, it is a large-bore cartridge delivering a heavy, sizable bullet at very high velocities. Its excellent stopping power and range also result in plenty of recoil and a distinctive muzzle blast, making it a poor choice for users prizing maneuverability and control over sheer firepower. However, it remains well suited for any inhabitant of the wasteland needing a round capable of stopping monsters, human or otherwise.
The basic .44 Magnum ammunition is a standard full metal jacket bullet: A soft metal core surrounded by a jacket made from tougher metal. This allows for higher muzzle velocities and greater damage, as well as increased performance against armor. The increased damage is reduced somewhat by the fact that the metal jacket limits the expansion, resulting in less kinetic energy transferred to the target.
Hollow point bullets feature a hollowed out shape at the tip of the bullet, causing the bullet to expand upon impact, delivering more kinetic energy to the target and disrupting tissue more extensively. However, this same property also leads to reduced penetrative power, as the bullet will be stopped by armor much more easily due to its properties.
The semiwadcutter is a .44 Magnum round loaded to combine the best properties of a traditional bullet and a wadcutter. It features a conical nose with a flat point, sitting on a larger cylinder, which transitions into a narrower end. As a result, rather than tearing into the target like a standard bullet would, the semiwadcutter punches a clean hole, with the middle segment of the bullet enlarging the hole. The result? A bullet offering superior damage and performance against reinforced targets.
In order to craft this ammunition, the player has to obtain the relevant schematics from Jules. Two skill checks (Guns 50 and Survival 60) are necessary. An alternative is selecting the Hand Loader perk.
The .44 Special is an older type of the .44 Magnum bullet, dating back to the early 20th century. It has a lighter powder load, resulting in less damage to the target, but also put much less strain on the weapon.

Rounds crafted with the use of scrap metal, these offer lower ballistic performance and significantly stress the firearm, but are better than nothing.
