Rolling my own with .223 for the first time. Gone are the days of old-timers laughing at me policing .223 brass. I saved it all, and now it's a great thing to have on hand.
Anyway, I just cleaned, lubed, deprimed and full-length resized 200 .223/5.56 and I noticed with the PPU .223 that it was a lot harder to resize (in terms of how hard I needed to pull on the lever) than anything else. It leaves a little ring down by the base which you can feel with your finger nail. I took out the trusty digital calipers and found them to be exactly in-spec for 5.56 NATO (9.58mm on the nose) at the base where the ring is and the metal is thicker.
All other brands of cases didn't experience this and came in below that number (Federal .223 Rem is at 9.47 at the base for example). PPU is marked "PPU 223Rem" on the head-stamp so it's not even a matter of 5.56 vs .223 other than maybe PPU is marketing 5.56 NATO ammo as .223 Rem?
Anyway, I wondered if anyone else had come across this and if they had any issues. See attached picture for visuals. Again, dimension-wise, everything is in-spec, so I don't see why there would be any issue, maybe the PPU brass is just a little thicker?
