    First off, cartridge cases are made of deep drawn cartridge brass which
    is one of many different brass alloys.
    The alloy along with the manufacturing process results in the strongest of the brasses. Cases are locally annealed during the deep drawing process to have a strong base.
    Too soft a base and it blows out at the base with catastrophic results.
    This has happened in the US.
    You can't duplicate the grain flow in a turned case.
    Bertram in Australia, I believe did some of that in the past on low pressure brass with poor results.
    You'd be far better off reforming existing brass.

    I had a 45-110 Ballard, I got 100 rounds of turned brass with the rifle when I bought it. I loaded some of them 20 times with no issues at all. I was very impressed with their quality and preformance.
    For what it's worth.

    If I'm not mistaken 45 and 50 caliber "basic" extra long brass has been around for some time now.
    It can be reformed and cut down to many of the old low pressure big bore calibers.
    I wouldn't use lathe turned brass for any high pressure calibers.
    In the 1870's and 1880's brass called "Everlasting Brass" was advertised.
    I suspect they were lathe turned.

    .50 Sharps WHAT?

    Starline makes drawn .50-90 2.5" when they get enough orders to bother with it.
    Buffalo Arms catalogs .50-70 and .50-90 by Starline, you would have to call to see if they really had any in stock.

    They also have .50 3 1/4" so called .50-140 if you need it.
