  It's been, what is called "swaged". Never have seen that type of swaging, before though. Very extreme appearing. Most of the time it's done with a hollow round punch. Around the circumference of the primer.
  
  Quite common in military ammo, fired in machine guns. So a blown primer, won't tie up the gun at an inopportune time.

  thanks guys, just have never seen it before, always ordered 5.56 and got regular ammo i guess with a normal primer pocket, is this better, worse, can it still be reloaded, as you can tell i don't know a lot about ammo

  The way the metal has been so extensively swaged around the primer. Might make the primer difficult to get out? With a full length sizer/ deprimer die. If so, I would first deprime the brass using a universal depriming die. Than full length size it in a separate operation. Than remove the primer crimp, by either cutting or swaging.

  That 4 pin crimp is a huge drag. I've experienced little issue de capping, but the brass around the cup is fairly well compromised and after swaging, leaves a pretty deep "cone" in the top of the pocket. This makes for a reloaded cartridge that is a little less secure than the circular crimp would be for a reload and increases the possibility of a primer leaving the cup and getting into your fire control group. Still works to reload, but it's a PITA. My pet theory is that the DOD has required it to make the stuff less utilizable to the masses ( I.e., you and me) for,reloading. Yea, call me paranoid, but I put little past our current " administration" as far as the depths to which they will go to deflower our Constitution.

  I would remove the 4 bar crimps, with a cutting tool rather than swage. To leave as much material as possible, around the primer pocket. Than use the primer sealing liquid. That is sold, to make the primer pockets moisture proof. Between these 2 steps doubt your going to have any problems with the integrity of reloaded primers.

  +1 on using a cutting tool to remove the intruding metal. I got a quantity of these in a trade a while ago. I used my Hornady CasePrep trio tool and they worked fine and some are into their third loadings with no sign of loosening.
