Had a friend go out shooting his AR and came back with about 20 or so rounds that seperated about 3/4" down on the neck. Any ideas as to why this might have occured? They were reloaded rounds. Thanks for all help.

    Either reloaded many times or worked the neck to much.

    Not enough information. Split neck or case seperation near the web is more common for been reloaded to many times.

    Perhaps it is a Bubba anneal job on the brass that went threw a SAW with more than optimial headspace.

    It wouldn't hurt to inspect the chamber and perhaps check the headspace. A review of the cases history and loading data woud be a good place to start.

    Ok, it appears to be only Winchester NT brass. Even on the loaded ammo we can see a ring in the brass where it is splitting. Will be picking those out and not taking a chance on them. Thank you for the replies.

    Since it is the same brass causing all of the splits, I am going to agree with Charlie that those particular cases were used in a SAW (which seems to punish the brass a lot) or other poorly-headspaced gun before you guys got it.

    The NT is the Non-Toxic loading now used at a lot of agency and Military ranges for training. The brass seems as good as any other Winchester brass according to posters on other forums I have read, and should last as long as the stabdard lead cases (provided the gun firing it is properly headspaced).

    I also agree that you should leave the "shiny ring brass" in the bag and not shoot it. IMO it's not worth the risk of damage to gun or person.
