Well , Not so fast Vizzio - Montana was incorporated as a territory of the United States in 1864 - and became a state in 1889 .
(The Civil War was 1861- 1865) - While there may have been no Civil War battles fought in Montana , It is not a stretch at all
to imagine any number of soldiers some years later being employed in the numerous Indian Wars and skirmishes that were
widespread throughout the territory . These men would certainly have carried whatever ammunition they had access to
including the "3 ringers" . Civil War period general service (eagle ) buttons are found in Montana for similar reasons .
