No. Even the most hastily gathered irregular units with the lowest priorities for equipment still had breech loading cartridge rifles. Several generations of cartridge rifles had been put into service between the last issuance of muzzleloaders and the advent of the then current M1903 and M1917 rifles, leaving a surplus of rifles sufficient to equip any auxiliaries without having to reissue muzzleloaders. Even the surplus breech loaed Model 1873 "trapdoor" Springfield rifles saw very little issuance, and that was to auxiliary forces which remained in the US.
