    Just a quick touch to the sander, not removing much. Blurs the head stamp enough and used for light plinkers only,primers sit flush still.

    I ended up making my own trim die from an old full-length sizing 8mm die. I annealed it and then cut it to length. After I polish it, I will reheat treat it. I have lots of Federal 25-06 & .270 to convert for CB use. No worries about headstamps that way.

    FL dies are case hardened low carbon steel so they do not have enough carbon on the cut off surface to be heat treated.

    So carburize it.
    I give loading advice based on my actual results in factory rifles with standard chambers, twist rates and basic accurizing.
    My goals for using cast boolits are lots of good, cheap, and reasonably accurate shooting, while avoiding overly tedious loading processes.
    The BHN Deformation Formula, and why I don't use it.
    How to find and fix sizing die eccentricity problems.
    Do you trust your casting thermometer?
    A few musings.

    Why take the long way? There is nothing to prove by all that work.
    Buy a trim die for $20 off ebay.
    If you are hell bent on doing it yourself just drop a hardened washer over the case neck to protect the top of the die.
    It is even faster to use a Wilson case trimmer case holder and part the case off in a lathe.

    Carburizing is not hard or expensive. I think he has already cut off the die. He obviously likes to make his own tools. Or remake them.

    Think like a handy retired person with fixed income but lots of tools. Then it will make sense.

    Why bother?
    I have done that very thing 40 years ago. It is not worth the trouble.
    Try thinking like a real tool maker.

    EDG- thanks for your input. I'll do what I want anyway as always. It's no bother.

    I've got a 9.3x57 Mauser and ordered some PPC 8x57 brass for it. I use that for all of my jacketed loads, but I wanted to try converting some 30-06 cases to use for cast.
    I started with some once fired Rem cases and just used the lyman case trimmer to cut them down to 57mm + a little.

    Next I lubed them and ran through the 9.3x57 sizer die and deburred the case mouth. A single pass through the sizer and they came out looking great.

    I measured the necks and they were .015" at the base of the neck, so they needed turning.
    I didn't have a 9.3 mandrel for the Hornady neck turner, so I opened the necks up with a 375 expander button.

    Then turned the necks to get .012" wall thickness.

    After turning the necks I ran them back through the 9x3.57 sizer die and did a final trim to get the correct lenth.
    With all of the sizing, I annealed the necks.

    I just cut to size(I marked on harbor freight mini saw), lube by spray, run them slow & steady through a FL die, then trim & prep as you would
    any other case. I dont anneal & I get many reloads in different 98 mausers.
    (I used to use a redding trim die before the mini saw, but saw is faster& no issues)
