The 44-40, or WCF, did indeed obtain speeds between 1,500-1,800FPS in 24" barrels, but not in 1873. That development occurred with the Winchester High Velocity loading that was put on the market ~1903.
The standard velocity of the 44-40 in its original, introduced blackpowder load was ~1350FPS.
My intention was to state that 44-40 eventually got to those powerful loads but the video itself implies that was the introduced velocity. Oops.
In this video we discuss the origins of the Winchester lever action rifle and the developmental changes from the 1860 Henry to the 1873 Winchester.
