Has anyone made 357 sig brass by running 40 S%W brass through 357 sig dies?

Patrick: I just read the other day, somewhere, that you can't get proper dimisioned cases for 357 SIG by using 40 S&W brass. Wish I could remember where & why. Perhaps the cases come up way too short?

It can be done. My RCBS .357 Sig dies included a piece of paper that said it could be done, and still maintain "proper functioning". It also noted that the cases would be approx. .018" less in length than .357 Sig brass.

I will tell you that I personally have used reformed .40 brass for LIGHT .357 Sig loads. You can just lube the case, and run it through the regular sizing die. That said, there is merit to sticking with .357 Sig brass for anything other than light loads. My measured re-formed brass was actually .022 to .025" shorter than .357 Sig brass. That's a lot. Also, the .357 brass is supposed to be stronger (thicker) than .40 brass. Given that this round is a fairly high pressure one, I want all the safety margin I can get.

I guess what I'm saying is that, for me, I no longer use .40 brass for this purpose. The price of .357 Sig brass from Starline is reasonable enough that I discontinued my earlier practice.
