I'm an old goat and thought I had seen it all but......people actually get angry about something like this?
My blood pressure was 120/70 today and there's a darned good reason for it. I blow off things like this and don't worry about it.
There is a .45 LONG Colt because folks like me want to identify it from other cartridges like the .45ACP.
It's like the "30 ought 6" but that's another story.
