This is the 3rd best gun for leaden salute as of 2016/01. It's behind mythic and perfect augment (AGI+23 MAB+25 WSD+7%)doomsday against targets with neutral mdb. If fighting against targets with high mdb, this gun may beat doomsday due to massive amount of mab. It also has awesome ranged dps in ranged dps heavy fights.
It's also the 2nd best wildfire gun as of 2016/01, 2nd to perfect augment doomsday. May be beaten by skill 269 Armageddon after Feb update though.
