Actually, I was one of those “kerfuffle-ized” for calling it .45ACP.
I was “informed” in no uncertain terms that the CORRECT nomenclature is “.45 Auto.”
I told him, “I don’t care.” Frankly, when I say “.45 ACP,” people know what I’m talking about, and it it pisses off the guy who insisted that I call it something else, so much the better.
I am aware of the importance of being quite specific on bullet diameters while reloading... Though things can get a bit touchy... For example, when I reloaded .357 mag or .38 special, I used .357 bullets, no matter if they were cast or jacketed. However when I reloaded 9mm, the cast bullets were .355, while the jacketed bullets were .356. And I don’t know why that was. Those were just the diameters of the bullets I was able to buy.
But while “Bench Racing” with guns, I’ve always been less precise than when actually reloading ammunition.

That's when I stopped posting to him. It wasn't worth the effort.
