I think speed of recoil, spring stiffness, and shape of both ejector and slide are all far more significant factors in brass placement than any fraction of a degree difference in bolt face / ejector orientation at the moment the spent case lifts free from the chamber and goes airborne. That being said, the brass ejection is a very "chaotic" system and I don't believe Ordnance Dept ever fully "resolved" the carbine's ejection "issues". It is what it is. While I've tried over the years to refine mine, I ALWAYS get the occassional "over the shoulder" case. Other than that, it's not "simple physics", it's actually "unpredictable"
