Heavy Caliber is a mod that increases damage of Primary Weapons (excluding Shotguns) at the cost of increased spread (reducing accuracy). Some weapons will have additional spread added, in addition to the base amount.

Notes[]
- Instead of reducing the accuracy by 5% per rank, each rank increases spread by a specific value per rank depending on the weapon. This effectively reduces accuracy but may reduce it by greater than 5% per rank (according to the Arsenal UI).
- Damage increase value of this mod stacks additively with that of Serration to a total of +330% base damage.
- Since the two stack additively and Heavy Caliber costs 2 more mod capacity for the same bonus, combining the two is slightly less efficient in terms of damage per capacity cost. Maxed Serration grants +11.79% bonus damage per 1 mod capacity, while maxed Heavy Caliber grants +10.31% bonus damage per mod capacity. Combining the two, Serration and Heavy Caliber grant +11% bonus damage per 1 mod capacity, which is +0.79% less bonus damage per capacity than Serration alone.
- The bonus damage from using Heavy Caliber with Serration is double that of using Serration by itself, though it comes at the cost of an additional mod slot and Heavy Caliber's slightly higher "base" drain of 6.
- For example, if base damage is 100 then Serration adds 165% bonus damage and Heavy Caliber adds an additional 165% bonus damage, for a total of 430 damage. Thus, bonus damage is doubled for roughly double (+114%) the drain cost.
- Accuracy reduction varies by weapon, even for those with 100 accuracy. For example, Ogris (which has 100 accuracy, decreased to 1.7 at max rank) rockets fly very far outside of the reticle, while Soma (which has 28.6 accuracy, decreased to 15.5 at max rank) spreads bullets considerably but do not stray too far from the reticle.
- The final accuracy after installing Heavy Caliber can be found by the following formula:
- Guided Ordnance can counter the accuracy reduction.
- The following weapons are unaffected or barely affected by the accuracy penalty:
- Acceltra
- Aeolak (grenade mode)
- Afentis (Primary Fire)
- Amprex
- Basmu (Alternate Fire)
- Fulmin
- Flux Rifle
- Gaze (Primary)
- Glaxion ( Vandal)
- Ignis ( Wraith) (Helps somewhat due to a wider attack radius)
- Kuva Bramma
- Lenz
- Mutalist Quanta
- Opticor ( Vandal)
- Penta ( Secura)
- Proboscis Cernos
- Quanta ( Vandal) (Primary Fire)
- Stahlta (grenade mode)
- Synapse
- Tenet Envoy
- Tenet Tetra (grenade mode)
- Tonkor (when arming distance is reached) ( Kuva)
- Vermisplicer (Primary) (Helps somewhat due to a wider attack radius)
- Zarr ( Kuva) (Cannonball mode)
- Gotva Prime
- While the center beam of all continuous weapons will noticeably wobble, they will stay within the reticle, making them more accurate than most other weapons.
Bug[]
- The accuracy stat in the mod's description uses the negative value of Ogris' spread value as a percentage.
Trivia[]
- When it was first released, Heavy Caliber's original penalty was an increase in recoil as well as damage. However the recoil penalty did not affect recoil-less weapons ( Flux Rifle, Ignis, Synapse, bows and Lanka among others), effectively acting as another instance of Serration. This was confirmed to be unintentional in Warframe Prime Time - Episode 2 (9:40). The mod's penalty was changed in Update 10.4 (2013-10-16).
