    We are just verifying the brands that we can use for production over the next couple of days. Then I will be starting production. I have seen the lists of head stamps that will work. I just like to check myself. If you want to help out, please measure the outside diameter of loaded rounds that works in your rifles at the neck. Post the brand, if it is converted .223 or factory blackout and the measurement.

    S&B has too thick of a neck if using Cast ( works if chamber is clean ) less so if dirty

    Winchester brass is Ok but I have been anealing them --- also the most found with cracked necks as 223 -- also crimped primer pockets
    Norinco ok but aneal

    RP Great brass but on the softer side

    I am seeing lots of FC 17 and FC .223 Rem headstamps. That will most likely be what I aim to provide.

    They both seem to land 0.330 - 0.331" with my measuring tools loaded with 150gr fmj. I have fairly accurate tools that are reading to 0.0001". With maximum at 0.334" I think that should be good.

    The first pre-production batch is going out to testers on Monday. Once it is verified, then I will be releasing brass en-masse.

    I ran into two issues that will increase the price slightly from where I had hoped. But really, we are talking like $5 per 1,000 increase at this point. Current pricing is looking like:

    $90 per 500
    $165 per 1,000
    $160 per 1,000 for large quantities

    One - I can't run as fast as I had planned. I was running around 2,500 pieces per hour, but shattered a carbide insert and destroyed a boring bar - so the actual cost of that plus the speed reduction to 1,500 parts per hour for the feed rate to reduce the thickness of the swarving to allow it to break apart for vacuum extraction.

    Two - Optical sorter for brass headstamp is slower than advertised. Actually operates at 1/2 of speed advertised to achieve the level of precision I demand. I aim for 99% headstamp accuracy, and if I run it any faster, then that accuracy starts to drop off quickly.

    In all reality, they are small issues. For example, I was processing 9mm today, like every other day. A minor problem is found with the machine, a case retaining bar looked a little out of specification. Pulled it apart and it is broken, the strip of metal is USD $190. If I go a week consuming less then USD $500 in parts across the whole fleet of equipment, it is a good week in my books.

    The only thing is that I have to pass on costs of specific items on that item. IE, the issues on .300 Blackout could be spread out across the whole product line, but that isn't fair. So I apply price increases against the specific setbacks.

    I will begin manufacture at the end of this week. I am closing out a 500,000 piece 9mm order and then I will have a bit of time to get this back into production. We are still waiting for final testing results, but should not be any issues as everything measured out within specification.
