Stainless/Aluminum hybrid cases to replace brass



  • Lots of pluses to these cases. No trimming, extended case life, extra case volume, marginally cheaper...etc.

    Even more negatives in my opinion.

    Case lube required even with carbide dies, proprietary dies required, can't be loaded in a Dillon due to proprietary belling die, no way to pull bullets without ruining "brass".

    It has potential...but I don't think it is there yet.

  • I don't think this will go beyond straight walled cartridges.

    I agree. I don't think it will ever take off at all.



  • Lots of contradictory "information" regarding these cases out there. Lots of bold claims on both sides.

    True data and experience, nowhere to be found.



  • If I'm not mistaken, this company originally were talking about rifle cartridges also. But as time has gone on they haven't been mentioned.

  • Plastic Combustible cases with just enough metal around the case head to seal the chamber and eject.

    Rifle cases would be more difficult as the dies have to push the cases out from the inside after firing or
    The case head will separate. does not mean it can't work...just not as easy.



  • Lots of proprietary technology required to use their reinvention of what is essentially ancient history technology with a change of materials from coiled copper to stainless steel. Hard to see how flexibility to allow chamber sealing can be reconciled with work hardening properties of stainless steel, you don't see a lot of stainless steel springs. Don't see this getting beyond initial investment stage. As soon as the seed money runs out it's over. In my experience, straight walled cases tend to shorten with use and bottlenecked cases concentrate their work hardening stress at the top of the web where thick, strong meets thin, flexible wall thickness. This makes me think the hybrid case will break on one or the other end of the primer tube, possibly not disasterous in a straight walled setting but a stainless cup pulled partially down a barrel and potentially closed on the breech end so that a conventional broken case extractor won't work could be a tricky situation to remedy. Steel cases are (maybe) fine for bullet-hoses where you expect to discard the barrel every so often but my lead bullet target barrels get 10s of thousands of rounds with no measurable erosion so I'm not anxious to have a steel case wearing on the chambers.

    Timin' has a lot to do with the outcome of a rain dance.
