Muzzle velocity of a 45

The problem is, a ballistic pendulum and a long test barrel were used to obtain those “defining figures,” and when original ammunition for the .416 Rigby was put through a modern chronograph, the results were eye-opening. Muzzle velocities of 2,150 to 2,175 fps were observed, lowering the energy values closer to the 4,000 ft-lb mark.

The .45 ACP is an effective combat pistol cartridge.

Feb 16, 2024 · The muzzle velocity of a .45 ACP (Automatic Colt Pistol) round typically ranges from 830 to 1,000 feet per second. This measurement indicates the speed at which the bullet leaves the firearm’s muzzle. I used to have a copy of a "Mil-Spec" sheet for 45 ACP Ball. It was dated 1968 (if memory serves). Velocity was to be 830 fps +- 15 fps. Anything from 815-845 fps would have been in spec velocity wise.
