Nah, it's just that there so much distance between the two launch lugs that when the upper lug clears the rod, any slight change in direction will cause the second one to bind. Rod whip can cause it. That's why you need such a large kick to get these long birds started. It reduces the lag time between the lugs exiting the rod.
