American US Civil War LEAD BULLET .55” X 1.10” Apache Indian Wars? Arizona AZ

Description

This three ring bullet measures approximately.55” wide by 1.10” long and measures 1-1/2" diameter. I found this using a metal detector in Tombstone. Arizona. I live 20 miles from the Fort Huachuca Army base which was very active in the Apache Indian Wars before and after the civil war. I found about 50 bullets in my yard and I’m assuming the former owner ( a collector, rock hound, and long time resident of Tombstone) found these bullets and threw them around his yard. He had a large Native American collection of found items, so I don’t know if these were from the Civil War or the Apache Indian Wars that took place all throughout this area. So I know nothing about this bullet but am happy to answer any questions.
I would love any insight or information that anyone might have.
