I started prepping some cases for reloading and came across something I've not seen before. When de-priming them, I noticed they were tighter than normal. Then after prep and clean, I went to prime them only to find that the primer wouldn't go into the pocket. I had to use my chamfer tool and remove the crimp around the pocket before priming.
Is this the same type of crimp used on military brass? I've never reloaded any military brass (yet) but have heard so much about the crimp.
