Hats Off to Webley, excellent explanation.
Here's why I personally don't like the 357Sig. I'm a handloader and I cast my own bullets. I loathe short bottleneck cases. That's a pretty triffling excuse isn't it, but it's the truth, I simply will not own a caliber that I would hate to reload. As soon as the fun gets sucked out of something that's a hobby, then it becomes work instead of a pastime. I got rid of everything I had in 7.62x25 for similar reasons.
Give us this day our daily lead.
