  1. I want to start reloading 357 SIG.

    I have read alit about resizing 40sw brass, however if I but 1x fired 357SIG brass is there anything special, other than of course running through 357SIG dies, that I need to do.

    I dont believe you can resize 40 brass, it wouldnt be long enough. Buy 357 sig and reload it as usual.

    There are some good threads about 357 Sig on this forum. The most important thing is using the right bullet. You should use a flat point or truncated cone to prevent set back. Berry's 124 gr FP works great and so does Precision Bullets 115 and 124 gr molly bullets. There are others listed in one of the threads.

    Another hint is to use a 40 S&W sizing die in station 1 and then you won't need to lube the cases.

    Here's a great place to get brass.

    It's a great round to reload and shoot.

    Good luck with it.

    There's no need to try to resize .40 brass. Given that 357 SIG brass is cheap and plentiful, why bother tinkering here?

    I use Dillon's carbide dies to load up my 357 SIG rounds, and use just a couple of sprays of Dillon's case lube (lanolin solubilized in isopropyl alcohol). Very smooth operation.

    Great to see that Vicky is still around. I remember buying lots of stuff from her a decade ago...

    Exactly right. Especially for a newb into reloading the 357sig, use the correct brass. Choose the correct bullet, truncated cone, set the dies up correctly, headspace on the small shoulder, good taper crimp. I also use the Dillon dies, but rarely use case lube. Any other die brand, you MUST use case lube. IMO, do NOT buy the RCBS dies, they got it wrong from the start.

    357 Sig is truely a reloader's round as it's cheaper to load up than 40 S&W, can utilize that 40 S&W carbide die if ya' got em, small pistol primers, and hella' fun to shoot.
