Automatic Colt Pistol. Colt invented the .45 Auto and thus had the right to name it.
.45 caliber ACP
.45 ACP
Caliber .45 Automatic Colt Pistol.
It sounds like maybe a .45 ACP. If the bullet is 11mm wide (diameter) and the case (not counting the bullet) is 25mm long, that sounds about right for a .45 ACP round.
No one. A standard .45 ACP bullet is about 230 grains. A .45 caliber bullet that only weighed 50 grains would merely be a very thin disk of lead.
Depends on which .45- 45 Colt, 45 ACP, 45 Magnum, 45-70, and which bullet, and what it is fired from. If you mean the .45 ACP fired by a 1911A1 pistol, velocity varies from 830 FPS up to about 1020 fps. Slow, fat, but gets the job done.
Answer The Colt .45 caliber automatic pistol was accepted as the standard side arm of the US Army and became identified as the Model 1911 Pistol. The bullet developed for use in this new design of automatic pistol was called the .45 ACP or the .45 Automatic Colt Pistol cartridge. It stands for "Automatic Colt Pistol" because it was adopted for the Colt 1911 only by the US army.You get many variants the most prolific being the .45 GAP for glock handguns.It's patented I believe.
Assuming you're referring to the 9x19 Parabellum/Luger round, the 9mm travels faster than the .45 ACP.
The answer varies, depending on WHICH .45 caliber bullet, and which weapon fires it. In the case of the 1911A1 pistol, in .45 ACP, firing a standard 230 gr. round nosed bullet, when elevated to 33 degrees, the bullet will travel 2096 ft. Not accurately, but that is it's maximum RANGE.
F.A. 43 bullet is a .45 caliber ACP bullet most likely from the Korean War or World War 2. The F.A. stands for Frankford Arsenal.
