Every time i go to walmart and ask for .45 acp they say they dont have any. But every time im there i see a few boxes of wwb that say .45 auto. Are they the same round? A buddy was telling me that some manufacturers wont put another manufaturers name on their product so instead of it saying 45 automatic colt pistol or acp they just shorten it to 45 auto. I just wanted to check with you guys before I bought any to see if this is true or not.

LOL, same thing, the clerk simply doesn't know that. It would be nice to see a clerk in any department that actually knows a little about what they are selling instead of having to say " excuse me sir, let me call the dept manager for you".

You will never find that at a WallMart, also, I figure it won't be long until WallMart starts selling WWB ammo made in China:biglaugh:

LOL............same thing happened to me a few months back. Everytime I went in and asked for .45ACP, I got the same answer...."nope". This was from three different clerks. Finally, one day I got curious about a stack of WWB 100 count boxes in the corner of the display case and saw they were marked ".45 auto". They'd been there since day one. Needless to say I bought them.....@ $32 a box I can't hardly roll my own.

The original name for the cartridge was:

.45 Automatic, Colt Pistol
over time it has become popularly known as
.45 Auto.

Same thing over time has happened with
the 9mm - originally called in EUrope as it was
first adopted by the German Army as
9mm Parabellum over time since it was used in
the Luger pistl it is popularly called 9mm Luger
and even labeled so here in the US. As a common
round used for NATO it is called 9Mm NATO
the european metric designation is 9x19 the 9 being
the bore and the 19 being the length of the case.

Metric def. for the .45 ACP/Auto gets a bit clumsy
converting to metric it is: 11.455x22.8 to be more
exact than whatever they round it to in Europe

Note: one of the most rare to have in a 1911
collection is the built under contract by the Norwegians
1911 that is the 1914 - I think there's two different
types, and they referred to the cartrdige as the 11.43.
and yeah the Nazis kept the manufacturuing plant going
after they conquered Norway so there are some
with Nazi Prooof marks.

9mm luger and 9mm NATO are actually different. SAAMI has 9mm luger listed @ 35,000PSI and 9mm NATO is 36,500PSI

My 2 cents

I don't know the clerk, but apparently he doesn't know 45s. "ACP" stands for "Automatic Colt Pistol." "Auto" is just short for the "Automatic" in "ACP."
You've been ripped off, my friend. Just be glad there was any pistol ammo at all in stock. Here in Vegas you can't get a darn thing.

But how did he get "ripped off"?

Well, not intentionally ripped off (hopefully). The guy told him they don't have any .45 Auto when there were several boxes of .45 ACP right there. He could have left with some ammo, regardless of the choice of words on the box.
