    Try this to find ammo. http://www.gunbot.net/ammo/357sig BTW, Bass Pro in Columbia, MO had a fair amount of .357 SIG, about the only pistol ammo they had.

    Re: 357 sig

    I was having custom barrels made out of 9mm barrels for the EAA witness pistols and for a while there, the only source in the country for .357 sig barrels for those guns (I think I still have one barrel laying around somewhere). One big issue I ran into was the case neck angle on those varied a lot not just between brands of ammo, but between different load styles from the same manufacturer. The gunsmiths had to be chambeing them differently too since some came back from the guy in Hawaii very reliable, and the ones from PISCO would only work with like one brand of ammo.

    I keep thinking that bottleneck cartridges and handguns just don't go together well. For that matter, Jeff cooper was really on to something with full power 10mm being standard issue for both a handgun and long gun cartridge.

    I had the same problem with the .400 Corbon, initially. I use a factory crimp die on them, but only gently. If you are over-crimping, you are actually losing surface contact area above and below the crimp, which offsets the value of a tighter crimp.

    It's a fine line. Once I got my crimp die set right, I never moved it again. I thought about using some clear Locktite (Superglue) on it, but I figure that would probably be overkill.

    The one benefit to learning on the .400 Corbon before I went to the .357 Sig was that setback on the .400 Corbon is a lot less likely to compress the load, so I got the bugs out without having to pull nearly as many bullets as I would have otherwise.

    That's my solution to the issue, but unless you have a batch of bullets stashed away already, 124g flat-nosed .356 dia ones are almost as hard to find as loaded .357 Sig ammo is.



    Ammo is scarce, and reloading components are just about as bad.

    I've been chasing 4064 or 4895 powder for the last 9 months, and haven't been able to find any of either yet. I can substitute for those, although it won't work quite as well in the calibers that I am loading.

    The depressing part about .357 Sig is that it pretty much only takes one type of bullet, and when that one type dries up, you are left high and dry.

    I've been tempted to see what it would do with some 115g Round Nose, but I suspect that I'll just wind up with a lot of set back rounds that I'll have to pull because they wouldn't feed right and got stuffed into the casing.

    Necked pistol ammo is hard enough to get right even with the right bullet, and I'm hardly having a shortage myself. (Hey....I only have two handguns in that caliber.)

    I love this caliber and it's dried up all of a sudden. Any one know where I can get some?
