"A 357 with the best loads out of longer barreled guns is a virtual tie with the 10mm"
No, the .357 will have more or no less energy, when comparing same weight bullets in similar length barrels. Once again, here are the facts from Buffalo Bore:
180 Grain JHP
1311 fps - Glock model 20 4.6 inch barrel
1337 fps - Colt Delta Elite 5 inch barrel
1351 fps - Para Ordinance 1911 with Nowlin 5 inch barrel
180 Grain 180gr. Hard cast LFN
4 inch S&W L frame Mt. Gun - 1375 fps
Accounting for loss of velocity between jacketed and hard cast they are similar or the .357 has more energy. The 10mm is a fine cartridge but let's not get carried away.

The Double tap 200 gr hardcast is rated at 1300 fps in 10mm. It actually chronographs at 1315 fps in my gun with a 4.5" barrel.
Their 200 gr hardcast 357 is rated at 1200 fps from a 4" gun, 1315 fps from a 6" gun. I've never chronographed any of it, but that is about as close to a virtual tie as you can get. But a much larger, longer revolver is required to beat a 4.5" auto.
My G-20 is a smaller package than a 3" revolver. In comparable sized guns the 10mm is at least 100 fps faster with the best loads from a 357.
