    Yes, big issue w/ the Speer nickel cases. A buddy even modified a decapping pin to fit.

    Thanks for the heads-up on the .357SIG cases. I've done Speer nickel-plated and brass .45 GAP brass on the Dillon without any problems (so far) but have yet to reload any .357. Most decapping has been done on my SS with a Lee universal die as of late to help keep the junk from building up too quickly on/under the 550 shellplate.

    If I run across it, I'll be sure to use the larger drill bit, as noted in your original post.

    I've decapped a couple of hundred Speer .357 Sig with no problem. All done with a Lee carbide 40 S&W sizer.

    Just loaded up 3K rounds w/ Speer 357 Sig casings from Top Brass.
    Indeed - the primer hole is somewhat smaller.
    However - the Dillon carbide resizing die has a very good pin and bored through every case. No other issues.
    All were done on my Dillon 550B.
    Dillon carbide dies are worth every dime when loading 357 Sig.

    Same here, no problems with the Lee 40S&W die.

    Well I was able to deprime many without issues but the Speer cases have very small flash holes, Just wanted to bring this to peoples attention! My Lee decapping pin got stuck tight enough to break it off inside the flash hole of one Speer casing.

    I hand deprimed all of mine and opened the holes to the same flash hole size as Winchester, RP and most others to eliminate any future issues!

    I even found a Remington which had a small hole...

    I reload nothing but 357SIG and nothing but Speer nickels--I've tossed everything else--and have loaded well over a thousand, one at a time. The regular steel Lee resizing die (which follows a pinless Lee .40S&W carbide sizing die in my Lee 4-hole press) has never failed or broken.

    This 'issue' is news to me.

    The early RCBS 357 Sig dies came with a larger diameter decapping pin. RCBS later changed to a smaller diameter and will send smaller diameters ones free of charge.
