Size, trim, and deburr.
Most likely many of the necks are not round. 10 in a bag? That's a new one on me. |

If you have a headspace gage and they all gage just fine, the only thing you need to do is run them through a neck size die OR run an expander mandrel through the neck. This will remove any irregularities and make the necks perfectly round.
From there you deburr and chamfer the case mouths. If you uniform primer pockets or deburr flash holes now would be the time for that too. You're ready to prime and load. |

I practically never full length size new brass, but I do neck size it, not only to round it up, but to make sure the neck tension is uniform. I'll make a wild ass guess that new brass has two destinations when it's finished - some goes to the manufacturing line for loaded ammo, the rest goes to the bagging line for reloading components. That means the case headspace and length is good to go. I might be wrong, too. If you deburr flash holes, do that first, then size as the guide mandrel opens the neck slightly. |

I've bought quite a bit of new 223 and .308 brass this year. Winchester, Hornady, Lapua, and Nosler. All four brands OAL was fine. Perfect in fact. All four brands needed neck sizing if for no other reason, distortion caused by shipping. Flash holes needed to be deburred with Winchester and Hornady as well case mouths chamfurred. The only brand that looked to be annealed was Lapua. I could be wrong and correct me if I am. Nosler, Winchester, and Hornady have been annealed after first firing.

I got burned many years ago with new brass.
Had 100 rounds primed, and powder dropped. Went to seat bullets, and they fell into the case.  ## bad words and a lesson learned.
To me new brass is brass that hasn't been fired. Not ready to load brass. So I size, trim, and debur before loading. Match brass gets the PP uniformed and flashole deburred. |

I have a few boxes of new Hornady brass and on the box it says "Properly annealed for strength & Hardness so you can reload again & again", so I assume they polish the annealing marks off the brass to make it pretty unlike my new LC & Lapua brass that has annealing marks from just below the shoulder up. The consistency of the Lapua brass I bought is amazing, of the pieces I bought every piece of it I measured is exactly 1.749" long with perfectly center drilled FH's and smooth(almost rounded) chamfered case mouths, I done good I think picking this 300 pieces of brass for $100 from a local supplier that had it stashed for a few years and had forgotten about it until one day I was there while he was cleaning up. |

treat it like once fired. I had some new factory IMI 762x39 brass and sized it. Some of the flashholes were clogged with burrs, the sizing process cleaned up the flash hole as well as took the dings out of the neck
