"A considerably heavier bullet, its mass and elevated muzzle velocity provides greater damage and increased range."

— In-game description

Magnum Ammunition (MGNM AM), commonly abrreviated to Magnum Ammo, is a specialization featured in Battlefield: Bad Company 2 and is unlocked at Rank 15. It increases all firearm damage by 25%.

Magnum Ammunition is canceled out by Ceramic Body Armor, because Ceramic Body Armor gives a health increase while Magnum Ammunition gives a damage increase.

Contrary to common belief, Magnum Ammunition does not affect bullet drop,[1] nor does it create vapor trails.[2] It also increases the damage of the Flamethrower, despite the Flamethrower not being a projectile weapon.
