    Do you know what Cartridge this is?

    I'm curious what the two on the right are next to a .22 LR for size, any thoughts?

    It might be 300 BLK now, but it used to be regular old 2012 Lake City Nato XM193.

                  The 4 point crimp is not very common. Are you doing forensics from a crime scene?

                    Could this be "NEW" LC Factory 300BLK Brass. Looks like the stakes were put on AFTER the primer was installed?
                    I know Federal made "NEW" 300BLK with a FC 300 headstamp, not sure about LC.
                    It's not the fall that kills you, it's the sudden stop at the bottom.

                      I've never seen a "4 point crimp"

                      Further, on the assumption that it was reformed LC brass, I was wondering how the reloader crimped it at home.

                      That's all.

                        It looks like the new mil spec for M855A1 ammunition. They want staked primers, LC/ATK stake the primers.

                          yep due to higher pressures from what I have read. I wonder if they pulled down ammo and resized without decapping/depriming
