***The other volunteer regiments had the 45/70 Springfield.***
IF I remember my history, Congress continued the use of the black powder 45-70 into the smokless era because there was so much ammo that need be shot up!
Army appropriations 1865-1898 were scandalously skimpy.
The Navy was well funded in the 1890s, which permitted the fighting of the Span- Am war in the first place. No Navy no war.
