Guys rememberr that when it all started projectiles mooved kinda slow and needed to be rather large to have any effect. As blackpowder improved and velocities increased bullet diameter was able to decrease.

In the Revolution muskets ran in the large 60's and 70's in caliber. When the 45-70 was adopted by the US ARMY after the Civil War the main concern was it's SMALL BORE size.

I think that the calibers "just grew" as was stated in another posting. Manufactures and "Wildcat" developers were able to keep decreasing bore size as the weapons became more efficient.

As far as MM vs caliber. English and Americans "used" to think in terms of the inch (100 calibers to the inch) European think in MM (roughly 4 calibers to the mm)
