If I had any interest in hunting, and could only have one, it would be the 357. About twice the muzzle energy and a much flatter trajectory than the 10mm.
Is that .357 out of a rifle?

dajowi "...relatively rare semi-autos."
Coonan is now producing its .357 semi-auto again.
My 140 JHP ammo gets 1464 fps with a 4" barrel. Comparing that to a mid-weight bullet from a 10mm may show that the 10 mm has an advantage. First, the bore is larger which at the same pressure produces more force to the bullet.
However, the 135grain JHP in 10mm has 50 fps lower velocity than the 140 grain in 357 according to the Sierra manual (5th edition 6th printing)
Again, the 10mm has more power
Not only that (in a fair comparison), but the heavy 10mm bullets (200gns and up) also have a wider surface diameter - which matters at real 10mm impact velocities on animals, ... 4-legged or 2-legged.
Again, the 10mm has more power
Not to pick on the .357 but comparing overall lengths, a new 4" Model 66 is still over an inch longer than a 5" M&P .40.
So the most equal comparison may be a 5" auto to a 3" revolver. The .357 can do great things but a longer barrel is almost a prerequisite.
One exception to this asymmetry, at least where the ".357 mag v. 10mm" debate is concerned (and you're genuinely interested in comparing apples-to-apples), would be a chronograph test pitting a 357 Coonan autoloader against any 10mm autoloader having the same length barrel, ... and see whose outcomes win the velocity/energy tests[/quote[
While this would be interesting it would also be of use only to those intending to compare the two rounds directly in very similar platforms.
As has been noted though we are not really just comparing 10MM vs .357. For instance though I own both the .357 (Ruger SP101 with 3" barrel) I have is likely not comparable to either 10MM. MAYBE the G29 with its shorter barrel but probably not the Delta Elite.
The G29 and .357 to me both represent the pinnacle of "do everything" guns in their categories. Both are capable, though less than ideal, as woods guns and both are capable, though less than ideal, as concealed carry firearms.
