Ejection pattern of the M1A1?

[JimF4M1s (Deceased)]

Only 11?? Some of us can't remember back that far.

As far as the action throwing the cases, should be the same. Though being as the M1A1 can be held in different manners, a person could have his face in a different firing position then with a full wood stock. I'm sure once struck, that would be adjusted.
