It may be one of those "gun" things.
In the reloading manual universe the family groups are fairly big with just the bullet diameter. Expanding into multiple bullet diameters can make things really unwieldy. Though I just learned how treacherous things can be with the .303 British.
There was a pretty good food fight on another thread a while back about the proper nomenclature for the .45 pistol cartridge.
The poster of the first part insisted the proper industry term was .45 ACP while the poster of the second part said .45 Auto was equally acceptable.
You can find commercially available ammo from reputable companies with either term printed on the box.
I stayed out of that particular kerfuffle.
Best regards,
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.
