Magnum ammunition is used for the powerful Magnum firearms, and usually the rarest type of ammunition. Depending on the game, they may become even harder to find in higher difficulty modes. Early Resident Evil games display Magnum ammo in either speedloaders or magazines, while later games depict Magnum bullets in boxes.
The Resident Evil Outbreak series depict Magnum ammunition in boxes. However they count as individual rounds, meaning each bullet must be manually placed in the gun. Fortunately these rounds can be loaded in magazine and speedloader items to quicken reload time.
The two Magnums in the Outbreak series both use different ammunition. .44 Magnum for the Magnum Revolver, and .50AE for the Magnum Handgun.
Resident Evil 4 features two types of Magnum ammunition, .45 Magnum for the Broken Butterfly & Killer 7 and .50 Magnum for the Handcannon.
Resident Evil Revelations limits the amount of Magnum Ammo the player can carry instead of taking up a space. However, the player can find Magnum Ammo Bag to extend the amount you can carry. One ammo bag can be found on both casual and normal difficulty, which expands maximum ammo to 50 rounds. Two additional ammo bags can be found on infernal difficulty, which make maximum amount 100 and 200 rounds respectively.
Resident Evil 6 yet again has two types of Magnum ammo, one which is the .50 AE Ammo while the other is the .500 S&W Ammo. The .50 AE is used with the Lightning Hawk while the latter is used with the Elephant Killer.
Magnum Ammo is only picked up in sets of 3 or 5. Handcannon Ammo is found in sets of 2, 4, or 10 and only drops when the player has the Handcannon in their inventory. Both ammunitions are stored in boxes that take up 1x2 spaces of inventory and hold up to 10 bullets in that much space. A single bullet of Magnum Ammo and Handcannon Ammo sells for 500₧ and 600₧ respectively.
