    Prior to reloading.

    Maxxtech 9mm brass with an internal “shelf”, presumably to prevent bullet setback.
    Drastically reduced internal case capacity and heavier bullets will crush case/tie up press.
    I have found CBC 9mm brass similar to this as well.

    That is why I use only the finest brass thanks to my local police dept.

    Lucky you.

    Used to have a resource for 9 and .45 brass; once fired Speer- LE range.
    Back to grubbing brass.

    Thanks. I'm good on brass but now I know to watch for any of those that might accidentally make it into the bag.

    Yes, I have seen some of it for the last couple of years. Its a pain in the butt...but it just means you have to be careful and sort the brass.

    It won't go thru station one on my press....resize and deprime...on Dillon 650. Press just "crashes" when it hits the shelf inside the case / so if you do miss one in the gets no further than station 1 least for me.

    And I thought 45 cases with small primer pockets are a pain. Thanks for the heads up.

    Dang! That seems like a lot more production expense for a non-existent problem...?

    I'm not positive ...but I think they use that shelf to make sure their bullets don't get seated too deeply. Their mfg equipment must not be very sophisticated....and they apparently don't care about the extra material expense.

    I forget where that ammo is made....I looked it up when I first saw them a couple of yrs ago...( getting old...I forget..)...

    I’d assumed it was to prevent setback and it would definitely establish COAL with bullet base contacting shelf.
    Also figured it may have been for use in subguns.
    Some can be rough on ammo.

    I bet you are right on with the sub-gun theory!

    That would make total sense.
