Any wildcatters out there? Last summer, while loading up some .357 Sig, I had a 10mm case get mixed in with my brass and didn't catch the issue until it was resized. Since then, I've been thinking that this might be the next big thing in pistols. How about near 10mm case capacity but pushing a 9mm pill? 9mm Magnum anyone?
At the very least, it would help to alleviate the neck tension issues that you have to watch for when reloading .357 Sig.
