The several "ACP" designated cartridges were obsoleted by the Sporting Arms and Ammunition Manufactures Institute (SAAMI) prior to WWII and replaced with the nomenclature "AUTO" Where have these people been for the last seven decades?
The basic problem is that most gun writers obtained their entire education about guns and ammo from reading other gun writer's tripe.
It is no more appropriate to use obsolete cartridge designations than to address a married woman by her maiden name.
And don't be fooled by the charlatans that the .45 ACP and .45 Auto cartridges are the same. They are not! They are built to entirely different technical data packages and different pressure testing systems and different pressure specifications. The fact that they looks similar is meaningless with respect to safety considerations. Same with .223 Rem vs. 5.56mm, Plus P vs. standard pressure loads, etc.
Please don't waste your and others time be seeking out and posting a list of other people or off-shore companies that are also ignorant of proper cartridge designations.
If you have a computer, you can Google saami.org and learn the proper and abbreviated names of all SAAMI approved cartridges. Or go to the American National Standards Institute for the same information.
It's the head stamp, stupid!
“Where have these people been for the last seven decades?”
Reading history books. No term is EVER obsolete.
“It is no more appropriate to use obsolete cartridge designations than to address a married woman by her maiden name.”
Unless you live in France, or are Catalan, or several other places.
