I only wish they made a carbide sizing die for the .357 Sig that was priced a bit below $100 bucks!
I was using a combination of .40 S&W carbide dies and standard .357 SIG dies. It worked but it took multiple passes.
Then I saw a guy selling "like new" Dillon carbide .357 SIG dies for $70 shipped. I jumped on that and they are out in my reloading area. I haven't actually _used_ them yet but I'll get around to it one of these days!
