High Velocity Ammunition increases the weapon's projectile velocity by 10% and minimum damage range by 20 meters, but reduces the weapon's maximum damage range by 2 meters.
Empire:
High Velocity Ammunition, often shortened to HVA, is an ammo type available to a variety of weapons. It is unlocked through purchase with Certification Points or Daybreak Cash.
While loaded, high velocity ammunition decreases the range at which the weapon deals its maximum damage by 2 meters, in exchange for increasing the distance until the weapon reaches its minimum damage, as well as increasing the weapon's muzzle velocity by 10%.
Although the weapon's maximum damage range is reduced, the greatly increased minimum damage range pushes the weapons's 'bullets-to-kill' breakpoints out to notably longer ranges.
