    See separation?

    What causes this? 7mmsaum. Full length resized. Warm but not hot load. 2nd and 3rd firing. Good Adg brass.

    Maybe your annealing technique could have something to do with it?
    I've seen it on a 223 where too many reloads and no annealing.

    I did anneal after one load. Maybe too hot?

    Brass is too hard/brittle

    It’s certainly the hardest/ toughest brass to FL resize with a manual press handle
    A big fast bullet beats a little fast bullet every time

    What do the bases look like?
    Just a question to get an overall picture.
    Also how many did you fire and have any others given you any sign or were these the first two in that batch that you reloaded.
    Again just for my own reference in what to look for, ie warning signs. Thanks.
    It's all fun and games till Darthvader comes along
    I respect your beliefs but don't impose them on me.

    Yes

    Most likely after annealing the cool down period was too quick

    ADG brass is well annealed before purchase so I would be tempted to load it 4 times minimum before re annealing

    Bases are good. No scribes or marks. I "think" it started after I annealed. Powder is Hybrid100V and R26. 162 grn at 3k out of 22" barrel so its up there. Have fired maybe 100 shots through the rifle and none of the brass is older than 4 firings.

    I will start again with new brass, not anneal, and track what happens.

    That’s not annealing, an instant cool is Tempering which will make the brass harder/brittle
