45 Colt vs. 45 LC

[grosland]

I'm interested in a slide action rifle. I've seen some offered in 45 long colt. However, none of my data books list that round, only listing a 45 colt. Is there such a beast and if so what distinguishes it from the 45 colt? I've got 3 Speer, 3 hornady, 2 Hodgdon, 1 WW, and one IMR manuals and none refer to the Long Colt.
Thanks in advance for any light you can shed on this matter.

45 Colt and 45 LC (Long Colt) are the same thing. The reason you see LC is because of the .45 ACP (Automatic Colt Pistol) which sometimes gets called "45 Colt".

Off Wikipedia:

The unofficial designation ".45 Long Colt" for this caliber originated amongst military personnel to prevent confusion with the smaller .45 Schofield. In reality, there is no such thing as a ".45 Long Colt"; only .45 Colt and .45 Schofield.

I'm pretty sure ACP is for "Automatic Centerfire Pistol". 45 ACP is never correctly referred to as 45 colt.

There apparently was a very short lived government reference to 45 short colt ammunition, compatible with both 45 colt and 45 Schofield revolvers then in service, and "long colt" was unofficially used to differentiate standard 45 colt from 45 short colt.

The correct name is "45 Colt".

I always thought ACP was Automatic Colt Pistol which explained why manufaturers other than Colt often designated the chambering as simply ".45 Auto". Kind of the same way the "S&W" is often dropped from .40 auto.

It is "Automatic Colt Pistol" for both the .45 and .38 ACP's.

Hope this helps.

Sorry guys, I stand corrected. I saw somewhere on the web that acp stood for auto centerfire pistol, but when I searched to find it again, I only came up with several references citing auto colt pistol.

The way I've heard folks use it, they say something like "He's got a .45 Colt" when they mean he's got a 1911.

Also remember, never ever confuse .45 Colt with Colt 45!

ACP does stand for Automatic Colt Pistol but that refers to the pistol not the caliber.
The correct designation is .45 Automatic or .45 Colt for the two cartridges.

 

[Sport45]

Are you sure about that?

What is the correct designation for the .40 auto? I always thought it was .40S&W.

I think the companies that develop new cartridges get to name them.

That is not correct. .45 ACP is the cartridge not the pistol.

John Browning is credited with having designed the .45 ACP cartridge. Browning's .45 ACP was built specifically for the pistol that many of us regard as one of the greatest pistol designs ever, the M1911.

The .45 ACP (Automatic Colt Pistol, 11.43x23mm) is a rimless pistol cartridge designed by firearms designer John Browning in 1905, for use in his prototype Colt semi-automatic .45 pistol—a design which evolved into the M1911 pistol adopted by the U.S. Army in 1911.

The .45 ACP would become one of the most successful cartridges of all time, among both military and civilian users. It has been used in innumerable handguns and submachine guns since its introduction.

Cabelas lists the ammo as .45 ACP also:

Matt-J2,

Thanks for the pictorial clarification. However, I often confuse the Colt 45 with that other great "40 oz. caliber" round, of course I mean the Old English .800
