Thanks, the box I am thinking about buying is marked with a lot number of RA5048, and looks to be identical to yours. I should probably do my homework to verify exactness of lot numbers with regards to it being military issue ammo.

IIRC I also read somewhere where this a slight difference with regards to the the top of the box as well........something either written or not written on the top of the military ammo box versus the similar style commercial ammo boxes. Maybe someone can expound further upon that?
