I have 300 pieces of lake city "11" headstamped NATO 7.62 brass that I have fired thru my socom m1a. I deprimed it, cleaned it in stainless media, full length resized in a RCBS .308 die, trimmed it to 2.005, chamfered, and deburred the necks. After all this I tried clambering a few pieces in two different .308 bolt actions, both I believe were chambered with a match/tactical reamer by different smiths and it doesn't want to chamber in either gun.
After, I took a few of the pieces and body sized it with a redding .308 body die with it bottomed out against the shell holder and they still won't chamber.
Do I need a small base FL resizing die or is something else wrong?
I have some Lapua brass that I resized with the same die and it chambers just fine. I did not fire the Lapua brass thru the m1a. Is the brass just over expanded from firing thru the socom's roomier chamber so much so that a regular sizing die won't properly return it to spec?
Thanks for any info or suggestions!
