I think making ammo in quantity is more likely to be the main constraint rather than the capabilities of gunsmiths. So if I was getting my warlord army started in earnest, after supplying my initial horde with flintlocks, I'd explore the technical limits of paper cartridges with the objective of getting as high up the ladder of rate of fire systems as I could on the spectrum from break-open to auto.
