Jst1Mr,
I've seen the same disconnect between specs on the Fiocchi, but don't know the truth of the matter. On the face of it, I trust the manufacturer's website more. Even at 720fps, it's a little faster than Remington or Winchester (both @ 685fps). I'd be surprised if Fiocchi went 100 fps higher to 780--in an FMJ, no less--given the evident concern about overtaxing the breaktops out there.
StoryforU, are you sure you're looking at .38 S&W, not at .38 S&W Special? I've definitely never heard of a .38 S&W loaded with a JHP, and I'd even be surprised if any cases were nickel, although I could be wrong. . .At the low velocities of this cartridge, it's highly unlikely a JHP would expand.
And yes, .38 S&W was/is often referred to as .38 "regular" or "short," to easily differentiate it from .38 Special. BTW, if you encounter old ammo, you may come across .38 Colt New Police, which is a 150g LFP that is interchangeable with the .38 S&W.
Note that the .38 Short Colt and .38 Long Colt are altogether different calibers--the .38 S&W Special was created by lengthening the .38 Long Colt case, just as the 38SPL was later lengthened into the .357 Magnum. Confused yet??
Final note: my nearby Bass Pro Shop recently had 5 boxes of .38 S&W made by Remington on the shelf. You may want to check them, as this caliber is otherwise hard to come by these days. As for me, I reload
