ACW and 1871 against the prussians, Minie balls or not.
rifled sidearms developed the true potential only with metal cartridges and bolt action breeches
another aspect is of course the artillery, and here breech loaders and quickfirers took some time too (de Bange obturator)
so as long as the firing range or the firing rate did not increase substantially, and the size of the armies was not reduced (mass-levy) like with the mainland European armies or in the Americas, we can regard this as the napoleonic shadow, I guess.....
