I'm not speaking of the platform Tonk, but the cartridge itself. I've never measured the capacity of the two, something I may have to do tonight, but my guess is the 357 holds more powder. More powder equals more power, unless some weird variables come into play.
A ten or more shot 10mm may indeed trump a six-shot .357 when the gun itself is factored in. I believe the .357 is a better cartridge overall than the 10. The 10 is a heckuva auto cartridge. It is what it is though.
