I recently acquired about 100 military ,once fired 30-06 cases. I've never seen other than LC, for the 7.62 or 30-06.Could anyone out there tell me anything about all or any of these headstamps ? they are, as follows : P8 ,88 ,HXP, KA, RB. They naturally have years stamped on them , like LC cases. I want to reload them. I'm , naturally, wondering about quality and safety. Thanks in advance for anything that you can contribute. Franf
