    Does any die maker make spacers that will allow one to use .40S&W dies adjusted for .40S&W to additionally load 10MM ? [RCBS doesn't]
    The spacers need to be 0.142" thick, the difference between 10MM and .40S&W case length

    Um, the dies sold as 10mm/40 S&W will load both cartridges?

    I use Dillon Dies and they are sold as 40 S&W/10 mm. RCBS Likely has the same?

    What are you using spacers for?

    Spacers, no. You're just going to have to manually re-adjust the dies every time you switch calibers. At least the sizing and decapping die doesn't move.

    You could use the .135" 38/357 ring and make another washer out of .007 shim stock from the auto parts store.

    Still, .007" is a mighty small amount of die height differance when it comes to a taper crimp die adjustment.

    I'd guess you could split the differance (.0035") on the die adjustment between the .40 & 10mm and get good taper crimps on both of them using the .135" spacer.

    There is probably way more variation then that in a sack of once-fired factory cases.

    Adust the dies as needed and forget the washer idea. Just keep a dummy round of each cartridge in your die box and set the dies to fit the dummy.

    Those of you who load .38 Special AND .357 Magnum using the same dies understand my question and why I need spacers for 10MM. I already use 0.135" spacers for .38/.357 that came with my RCBS die set but apparently no die manufacturer has made sumilar, 0.142", spacers for .40S&W/10MM. RCBS says they never thought about it. Guess I'll have to make my own spacers.

    Don't know what press you are using, but placing a couple of nickels under the die lock ring will get you .140" spacing. Brand new nickels might get you the exact .142".

    I have the Redding .38Spl/.357 & .44Spl/.44Mag spacer sets, but I also bought a set of spacers that went from .001 to .125, and it comes in handy. I wish I remembered where I bought it.
