1. An air gun comprising:
a barrel having a volume;
a bulk air supply configured to store pressurized gas;
a shot reservoir configured to store pressurized gas and provide a pressurized gas supply;
a pressure regulator configured to provide the pressurized gas supply to the shot reservoir at a predetermined pressure from the bulk air supply, wherein said predetermined pressure is less than a pressure of the bulk air supply;
a valve assembly configured to provide pressurized gas from the shot reservoir to the barrel when triggered, wherein:
the valve assembly is the main valve assembly of the air gun; and
the shot reservoir has a total air volume from a main valve seat of the valve assembly to the regulator of at least 1.5 times the volume of the barrel.
