There is no short colt either ,but if you had a calvery unit using the top break Schofield and you were sent 45colt ammo you
would damn well be telling them to send you the short colt!

But if you had a 45colt revolver you could use either!

So yes there at the time in question a long Colt and a short colt
round was made!

Of course the longer colt round was just the 45Colt!
