Holy smoke, bang and flash Jim, that was interesting and maybe demonstrating my naivite about pistol rounds, but reading those charts, it appears the 9mm outperforms the 357 in terms of muzzel velocities pushing similar grain sized bullets up until the barrel reaches 5 or maybe 6 inches (they both appear to outperform the .38 which made more sense). I'll need to spend some more time with side by side comparison when I can cut and paste into a spreadsheet (geeks with guns). All the same pretty eye opening.
