    Gosh, that's a tough one. You got me! I think it takes a .40 shell plate/holder, but what die---hmmmmmm?

    All the major die makers produce dies for the 357 Sig round. I've got them from Redding and Dillon.

    Don't waste your money on the Dillon Carbide dies. For one thing, they don't contain a neck expander, since they're designed to work with the Dillon powder through expander, which I don't use. They're also about double the cost of good Redding dies.

    If you already have a carbide .40/10mm sizing die, you can presize the fired cases through that die and then finish them in the steel 357 Sig die and only size the neck and put the shoulder back where it belongs.

    If you do decide to load this round, treat it just like your bottlenecked rifle rounds. Chamfer the case mouths and consider both the case mouth and the shoulder as datum points when sizing.

    Once you get into it, there are several on this board who load 357 Sig and are willing to help.

    Hope this helps.

    I use a 40 S&W carbide die for the initial sizing. This eliminates lubing the cases.
    I finish up with 357 Sig dies.

    That dang near put me on the floor:neener: Please excuse me, as I have used up my alotment of tact for the month, but wow, that hit me as amazingly funny.

    On a more positive note, just about all die makers have dies for 357sig and there is lots of help available if you need it for this caliber. Best of luck to you. :)

    I've never heard of one. My guess is it would cost the same to make a neck sizing die as a regular full sizing die, since they both have to be reamed. The shoulder also has to be set back in a lot of cases, so a sizing die is in order.

    Hope this helps.

    Perhaps a die that only sizes half way down and not fully? I have heard of this in other pistol calibers.

    G'day.
    I've been loading 357Sig for awhile now.
    I use 40S&W cases necked down and loaded as 357Sig.

    The neck is a tad short, but the rounds headspace at the shoulder.
    All the 40 brass is pushed thru a Lee 40 FCD with the crimp parts removed. This removes the "Glock Bulge" from the cases. They then get sized with a Dillon Carbide sizer die.
    I the load the ammo on a Lee Loadmaster with a Lee Sizer, Dillon Powder/expander die and powder thrower, Dillon Seat die and lastly a Lee FCD.

    So, All my 357Sig loads are based on 40S&W cases. No problems at all with Major Power factor loads.
