Standard venting is 2 spirals 3 inches long. - What does venting do? The gas travels faster than the ball, thus knocking it off course when the ball exits the tip. Venting dissipates that blast behind the ball creating a less turbulent cylinder of gas. This helps keep the ball on course and reduces the report.
