A 10mm field revolver should be chambered in 10mm Magnum and if it's a DA, the cylinder rebated for moon clips so .40 standard 10mm loads can be used. A single action 10mm Mag, with a spare 40 S&W cylinder, would handle everything from mice to moose if a fella reloaded for it.

Wasn't aware of the 10 mag but that case looks to be a perfect pattern for a 10AR as you say. Reading Starlines specs for the case length it's +\- that of a .357. And that GP in 10mm is veddy veddy nice. Should be able to juggle the magnum case length to make auto rim COAL fit a standard .357 cylinder. What kind of pressure comes with a 200gr bullet at 1200fps from the mag? Got a Trooper Mk lll that could be modified if the cylinder walls could handle it. But on your idea for an extra .40 cylinder, I just saw a used Blackhawk .357 on GB with an extra cylinder in 9mm. DONOR !! I'm liking this a lot.
