Does anyone have specific info or a link you can share, that would give the service of the Pack Parrott Rifle? I have done a site search, Google search without finding much. What I did find on Artillery Forum was limited. A patent drawing exists from 1862, but opinions vary from there. Some feel none were ever produced, others indicate limited production. Most opinions say they never say action in the field although one fellow claims they were in at least one battle but no specifics were offered. Some indications are that they saw service with Cav units. Other opinions indicate they were used in the Indian Wars on the Plains following the ACW. Any more that anyone can offer?
