Dude read my previous post. It adds and extra step to the reloading process. That means it's more involved than reloading let's say 9mm. Mmmmm-kay? That's the short explanation.
A lot of presses can de-prime and re-size a straight walled case in a few simple steps. You can use a carbide die to re-size.
With .357 sig you have to use rifle bottle neck reloading procedures. There are no carbine dies for .357 sig. You have to lubricate the case and use a bottle neck re-sizing die. Then you have to remove the lubricant. So you have to tumble it or take a towel to each individual casing. If you don't get the lube off and it ends up in the primer pocket you have a problem.
Then there's the problem of case length. Bottle neck cartridges will stretch upon firing. You don't have to worry so much about trimming straight walled cases. All .357 sig cases must be properly trimmed because the shoulder of the case had to bear against the chamber. It also has an extremely short neck with little space to grip the bullet. If you're not very careful you'll end up with case head separations.
There's your explanation of why it is more difficult to reload compared to other straight walled case ammunition like 9mm etc.
