I'm new to reloading (everybody is once). I have an XL650 Dillon and reloading .223. It's been going ok, but was having a hell of a time with the primers. some went in just fine, some did not. I had no idea that I had a bunch of military cases. Although I've read a lot about it, and even purchased a dillon super swage (for the day that I purposely bought militay cases), I didn't realize that I actually had a bunch of it. I watched a youtube and saw the NATO stamp. I checked my cases, and sure enough, they were crimped. I've disasembled and reasembled my press, prepped the hell out of the cases, read every blog and tid-bit of info I could find, and nothing worked. Turns out with one pull of the swage lever, all my problems went away. I actually laughed out loud. I learned a lot this weekend! good times.
