I just got an email from Ruger listing their new goodies in Winchester's new .350 Legend cartridge - looking it up , it appears to be a rimless .357 Maximum. Case length is 0.10" longer than the Max and the case has a slight taper (.3900" base to .3792" neck), but bullet weights & speeds (from rifle-length barrels) appear to be the same... Could be rather interesting on an AR platform!
Of course, I just sent the barrel from my Henry .357 Magnum single-shot out to be rechambered to .357 Maximum...
One nice potential side-effect for .357 Maximum shooters / reloaders would be increased availability of light (< 180 gr.) .357 bullets capable of dealing with rifle velocities; ones designed to be effective at pistol speeds generally don't do too well at 2000+ fps. (The Nosler 180 gr. XTP is about the best choice now for the Max.)
