Like Miller, I'm of the thinking that the watertable to breach angle is irrelavent. I (also) believe it's the angle 90 degrees from the line between the axis of the barrel hinge and lowest breachface contact point that is relavent. The breachface must be over 90 degrees (more open) from this angle to open and close.
