Hello everyone, I was reading up on some ballistic information in attempt to convince myself out of buying a midsize 357sig gun when I already have a 40SW (sub)compact gun. No I can't swap the barrel, they don't make it. Since I have a 40, I paid close attention to its performance particularly the ones mentioning/mentioned by FBI because that's what made me want more power (10mm) in the first place. And while doing it, I found this.
(Google "FBI 10mm notes" for source)
KEEP IN MIND - these are old. As in, they didn't have Gold Dots back then
But anyway if you just spend a minute or two shopping for 40SW ammo, FMJ for plinking or JHP for defense, they all push 180gr bullet over 1000fps.
At least Speer does, (sorry I am a little fanboy) http://youtu.be/39NDONv3MQY?t=1m40s
It makes all sense because 10mm was too big for most agents to use at full power anyway, they decided to bring the dimensions down to get rid of unnecessary space.
But I'm nervous to ask, can I say "Modern 40SW ammo performs comparably to the 10mm FBI in the 80's, if not better." ??
Thanks for reading.

Now, please refrain from passive-aggressively ing the calibers that you don't own, as we don't need another battle of the calibers, but the bold part got me very interested, also crushed my attempt in justifying owning a 357sig (which is weaker than full power 357 mag to begin with). Yes I've said I'm trying to talk myself out, but I think we all can agree, it's a two way road......9mm - the Federal 147 grain HydraShok
.45 - the Federal 230 grain HydraShok
10mm - the FBI load, a 180 grain Sierra bullet at 980 feet per second
.380 - there isn't one. The full metal jacketed round is the best of a bad choice, but only because it might penetrate.
.357 - we haven't found one that is sufficiently better than the best .38 load to justify all the sound and fury of shooting it, unless you need the increased effective range, which the higher velocity gives you. We have only tested five so far, and none of them stands out.
.38 Special - the Federal 147 grain HydraShok
