Well, the 9X25 does have more case capacity, so it can be loaded to produce higher velocity than the 357 Sig, but for what purpose? It's a wildcat cartridge, no factory ammo or even brass is available. That's why it's just something to play with.Originally posted by Frank Sottile:
Lets see, take a 10mm case and bottleneck it to 9mm, sounds a lot like that "NEW" 357 Sig.
What's OLD is NEW again.
Is there any REAL diffreance between the 9x25mm and the 357 Sig?
