The hollow-based conical bullet expanded on firing and gripped the rifling of the barrel; a percussion cap replaced the flint. Brazil used mainly Minié and Enfield muskets, and the Argentine infantry had mostly rifled percussion arms. Paraguay had very few: at Tuyutí only three battalions were not fighting with flintlocks.
