The siphon tube defines a passageway having a first end portion which is adapted to communicate with a shot cylinder and a second end portion opposite the first end portion which defines a molten metal entry portion. The passageway tapers from the first end portion to the second end portion which reduces jetting in the shot cylinder. An associated method is also disclosed.
