Ammo Bonuses apply single-mission effects to shots fired from weapons. A weapon imbued with an ammo bonus will apply additional ammo damage that is separate from impact damage. With the exception of Incendiary Ammo, which applies a damage-over-time effect that lasts 3 seconds, ammo damage is applied before the impact damage. Only a few weapon damage bonuses improve ammo damage; usually, it will be the listed percentage of the weapon's base damage. Ammo damage is very heavily affected by the target's current defense and with most ammo types, there will be 0 ammo damage to certain defenses.

Notes:
Contrary to the in-game description, Incendiary Rounds apply only a damage-over-time effect, doing 10/20/30/50% damage over 3 seconds[3].
There's a buggy damage recalculation when re-applying Incendiary Rounds on a target, allowing them to reach up to triple damage with constant fire.
Incendiary Rounds prime Fire Explosions after doing 30 points of damage [4].
Incendiary Rounds will permanently prevent the health regeneration of enemies such as Cannibals and Phantoms.

Note: Phasic Rounds also carry a 10x damage multiplier against shields and barriers, making weapons effective at bypassing enemy shield gates.[2] Phasic Rounds grant no extra damage against armor, making Disruptor Rounds significantly more damaging against armored targets by comparison, even though they are less damaging to shields and barriers.

Notes:
Warp Rounds also carry a 2x damage multiplier against barriers but do no extra damage against shields. This can enable weapon fire to ignore damage bleed-through penalties, though only against barriers.[2]
The Biotic Damage Bonus is applied as an additional ammo-damage bonus against any target which has been primed for a Biotic Explosion. After detonating the explosion (or if the priming effect wears off on its own), this additional bonus will no longer be dealt.[5]
The armor-weakening effect also benefits allies.
