    The standard magnum type brass is not obsolete or scarce !

    I just ran across a magazine article on forming .43 Spanish cases. It runs from page 34 through 39 in the April 2001 issue of Accurate Rifle magazine. It looks like everything in it has already been covered here, though.

    Good afternoon
    With one Roller in .43 (With a .444 Groove) I learned that before you start work on the 348 Win Brass rim see if the case head already fits the chamber. We still have 3 Rollers in ".43" and they all have a groove .442 or larger.

Step 3 was resize with the decap/neck size plug in place. Trimmed the belt off the case on my lathe. I suspect a drill press with a large enough chuck to hold the case and a file would do.

    Finding the right circle clip took a little time and I wasn't smart enough to write down the size in the hardware store when I was there.

    I've only made a couple, but it certainly looks like viable method of making an expensive case from a commonly available case.

    I've got 60 more 300 win mag case that I have no use for. At least until now

    The only way I found to form 43 Spanish involved a lathe which I don't have although that would give me an excuse to buy a lathe

    Buy the brass from Track of The Wolf.

    Glad to see I was of help. I used a tapered mantrel inserted in to the case month when fileing off the belt in my drill press.
    Just do not forget to anneal that brass before using it. I forgot the frist time and lost some to shoulder splits . once I started the annealing I haven't lost any , some have been fired 5 times using 5477 powder

    First half dozen conversions were with Hornady brass, worked great. Figured I had the procedure figured out. Wrong. Next 20 were Winchester brass. All steps except trimming the belt off completed. Trimmed belt on the first case, won't chamber, too fat ahead of where the belt had been. None of the others fit.

    Back to the drawing board. Tried Federal brass, 20+ pieces, all fit great, single piece of Remington brass doesn't even need belt turned off. I think I need to scrounge some more Remington brass.

    Dang fat Winchester brass.

    I found it best to size the brass in mag type full lenght sizer die before sizing in the 43 Spanish Mauser die.
    I have been using a Lee 7mm mag die to do this, worked for me . Hope this helps

    You have a bit of a point but I stumbled across something in my musings...

    The .50 Alaskan is based on the .348 Winchester case, is available and far less expensive than the .348 so how much effort would it be to size it down instead of blowing the .348 out?

    The circlips on altered mag rifle cases work just fine. I got my clips from McMaster-Carr:

    I know your experience. I bought a German stalking rifle (pre 1890, no proof markings) that was advertised as a 8mm. It turned out to be a 9.5X47R chambering. Making brass has been an interesting experience. BACO 44-77 with a .513 base diameter is where I'm starting with as parent brass after chamber cast. 375H&H dies taper the body. I gut lucky and found a used set of 9.5X47R dies on EBay.
    Lee dies won't hold up reducing the body diameter they will split.
    I used 45-2.4 (45-90) to make ten 43 Spanish because of a need to know. But I will use the BACO with the .513 base (at the time were $178 a hundred shipped) if I make more.

    Don't bother with the 348. I wasted money on that. I was successful making 43 Spanish out of 45/90 and even 45/70 with a short neck. Both shot fine, and needed nothing more than a full length die. There is even a 45 special or something like that that is just a long straight wall 45 case that can easily be formed to 43 Sp. (or 45/70, 45/90) Half of my cases are these.

    every time that I used 45-70 brass. I just run them into the 43 SPANISH, dies and a beautifully formed case came out. up on firing them every one of them split legenth wise. not good to use 45-70 at least for me. any one else have this problem?
