I find it interesting that folks don't like the .40 S&W, but when you add 100-150 fps to the cartridge, it becomes the equivalent of a hand held ICBM launcher. It's suddenly a "powerhouse", and a "beast".
a hot .40S&W MIGHT make 500ft/lbs muzzle energy.
a full house 10mm WILL make OVER 700ft/lbs muzzle energy.
that's the difference from .380 to 9mm, or .40 to .45acp.
Really? Just to back what I said:
From Hodgdon's website (top load/velocity listings):
155 gr bullet
.40 S&W = 1283 fps (energy 566 ft/lbs, momentum 28, Taylor KO 11)
10mm = 1362 fps (Energy 638 ft/lbs, momentum 30, KO=12)
.45 ACP = 1185 fps (energy 486, momentum 26, KO = 11
180 grain bullet
.40 S&W = 1159 fps (energy=536, momentum=29, KO=11
10mm = 1287 fps (energy=661, momentum=33, KO=13)
.45 ACP = 1087 fps (energy=482. momentum=27, KO=12)
Since you used energy figures, lets go with it. Energy has nothing to do with bullet diameter, but has everything to do with velocity and bullet weight. That being the case (pun not intended), the .40 S&W actually has HIGHER energy levels than the .45 ACP. The .40's bullet will have a higher BC, SD, and the handguns typically hold more ammo.
The 10mm is that much better yet, and it's certainly an impressive cartridge, but that in no way makes the .40 S&W any less than it otherwise is.
The 10mm, at it's best (that means hotter loads than I've listed from Hodgdon's that are not "commonly available"), it's the equivalent of a full powered .357 magnum.
That's impressive, but not "awe inspiring".
As an interesting tidbit, here's how the top listed 9mm load(s) compare from the same site:
124 grain bullet
9mm 1169 fps (energy=376, momentum=20, KO=7)
147 gr
9mm 1004 fps (energy 328, momentum 21, KO=7)
