Pardon my ignorance, but I wondered if the common term ".44 magnum" refers to the .44 Remington Magnum or if it's another cartridge. My reloading book only shows loading for the .44 Remington Magnum, so I assume that's the only standard cartridge out there. I'm not a pistol guy anymore, so I was just curious. Kind of like when people say "45 long Colt". I'm told it's a misnomer, since the two Colt cartridges were .45 ACP and .45 Colt. So, if one of you kind folks would take a sec and clarify that, I'd appreciate it.
