    Ran across this case last night reloading a batch of 9mm. I’ve never seen this before. The picture may not do it justice but it looks like there is an additional lining or second case wall at the bottom.

    Wondering what this is and if it’s ok to load?

    Surely has to be to control seating depth. I'd load it.

    There have been several threads on these "shelfed" cases. Some worry about increased pressure due to the reduced case volume due to the shelf. It's your choice.

    I toss 'em as I want the flexibility to choose a COAL of my own liking.

    Just because I am interested, will a bullet seat to the proper depth in the case?
    I have not found one in the cases I have looked at.

    It will obviously depend on the bullet.

    If I had some, I would load them. I think I would probably use the published minimum powder charge.

    In addition to the reduced capacity that can spike pressures, they have a nasty tendency
    to break right at the step after a few reloads and leave the forward part of the case
    stuck in the chamber. I've seen several--and they can be a real pain to get out.

    I toss them.

    You just can't improve on the voice of experience. The odds of me ever loading any 9mm are....non-existent....but I'll remember this. I would never have thought about a case separation at the point of the ledge.

    I've seen several threads on this "shelfed" case, mostly in 9mm (Maxxtech?). The consensus seems to be the internal dimension of a "shelf case" vs a standard case is reduced enough to produce too high pressures, so most toss them. I haven't run across any but I don't think I'd reload them. With 9mm brass so abundant why use an "odd" case with a possible risk?

    Thanks all for the quick reply’s. Pressure and case splitting issues were my concerns too. Tossed it today to be safe

    To make matters worse...according to a 2017 thread on Brian Enos's forum, these are brass coated steel from Freedom Munitions. Should never be reloaded. Check to see if it is magnetic...it most likely is.

    I have no experience with this, but thought it worth sharing. Prone to separation as has already been mentioned. Why they didn't take the precaution to Berdan prime these is beyond me.

    I like others toss them, 9mm brass is plentiful for the most part and not worth the worries of what might happen with a stepped case.

    Tain't no way I would reload them. Never seen enough of them to worry about. I'd just throw it in the scrap bucket.
