D.Mighty where did you obtain this information. I am intersted in this as well. I would like to know for sure since I am buying an le 6920 tomorrow or the next day. If there are so many options available and the chamber can mathematically and by design support the different brass and calibers why do we not hear much about it. I would totally love to figure out how to shoot cheap 9mmx19mm pistol rounds through it. But how?
