I picked up 100 Hornady 6.5 cm cases off the range a few days ago. I went to full length size them today in a Redding fl die and they were really hard to size. They will chamber now but they still seam tighter than all of my other cases. Even during sizing I was having trouble with the range brass buckling necks. Should I dump them? I am thinking who ever fired them had a really loose chamber
