Not quite the whole story. There was a round that was called the 45 Colt Government. Shorter than the 45 Colt and loaded with 28 grains of BP using the same 250 grain round nose. Discontinued well before WWII, and not seen since... except:
The Long & Short of the .45 Colt. But even that does nothing to alter the fact that 45 Colt is the name of the cartridge under discussion. No "long" about it.
As for a bullet in the 45 Colt? I happen to like the ~228 grain TC I get from the RCBS 45-225-CAV. It has a nice wide meplat (wide enough), a good sized grease groove suitable for smokeless or BP, a crimp groove... and feeds like a champ thru any of the 5 - 45 Colt leverguns I have. 1 - Rossi, 2 - Ubertis, & 1 Marlin. With 37 or so grains of 3F or Goex "Cartridge" in modern cases, it smacks with authority. None of the critters I've shot so far have gotten up and laughed.
