    I think my LGS has a bag of brass. Not cheap though. Probably around $80 for a bag of 50

    When my 358 Norma was a 350 Rem, I used 300 Win brass. You have to wipe off the lube fron the shoulder area or you will get some serious dents in the shoulder I started with the seater die for the 1st pass, because it has a more generous tolerance. Take it slow, I got my best results in 3 passes, wiping the shoulder every time and trimming ALMOST to length after the 1st or 2nd pass. It's a PITA, and that is why my rifle is not a 358 Norma and because my rifle smith(Jimmy McCoullough ) had a reamer and does killer work. Milltownhunter, If your rifle is a long action, the 358 Norma is a lot easier to form and you can always load it down to 350 Rem speeds. Just my 2 cents worth.

    Nosler lists .350 Mag. though they are currently out of stock.

    I use RCBS FL dies MOSTLY though I do have other brands. I have many sets and I have no chambers that require a small base die.

    I have formed a few .350 Mag cases with a RCBS FL die without event.
    Were I to form a lot of them I would use one of my .33 Win form dies or a 38-56 form die to get a large diameter neck pushed back before using a FL die.

    Just a little input based on observation from one day at the range.
    I have an unscoped Browning BLR in .358 Win and a M70 Win in .375 H&H.
    I shot both at the range one day. In the light BLR I shot 250 grain bullets. In the heavier .375 I shot 235 and 270 grain bullets. It was my impression that the .375 was more pleasant to shoot than the BLR.

    I wonder if reforming 338 wm brass would work easier?

    OR you could find some 6.5 Remington brass and just expand the neck. My BIL does that. Very easy.

    That would be easier than my experience with 300 win brass. I use 338’s for my Norma and they work just fine with 1 pass through the sizer.

    I've made 350 brass from 338 using a RCBS FL 350 sizing die.
    Just pull the decapper/expander assembly, lube the cases and then run them into the die to the shell holder.

    Ive had a 350 mag since 1976 ,I also use a trim die to make casings , using the trim die first , then trim brass and resize in regular 350 mag sizer die.
    I have tried 7mag and 300 mag brass all work but 338 win mag is the best/easyist to make casings with.
    I just saw somewhere in catilogs new 350 mag casings are available through mail order

    I made a few 350 Rem Mag out of 7mm Rem Mag using a Redding trim die, just to prove I could do it. It turned out to be a lot more work than I thought it would be. One pass into the trim die, hack off necks, run through a full length sizer, trim cases, outside turn necks. The next time Remington made a run of 350 brass, I bought a lifetime supply.
