The Wyvernheart is the special ammo type that allows the heavy bowgun to fire similar to a machine gun. The longer the fire button is held the stronger each bullet will become. The downside to using this is that the your crosshair will move wildly depending on how high the Heavy Bowgun's deviation is.

This Special Ammo Type is the most effective against slow or stationary targets where you have a lot of time to shoot the monster.


The Wyvernsnipe is the second special ammo type which allows the Heavy Bowgun to fire a single round which pierces the monster followed up with multiple explosions depending on how many times it pierced the monster.

This Special Ammo type is the most effective when you shoot across the length of the monster to maximize the number of times it pierces the monster.
