Grapeshot or Cannister Ball or something else?

[howardscalls]

Hello this is my first time posting , I need help identifying a ball, this was found in a farm field in rural Southeast Wisconsin, The ball measures 2.1 on my calipers. I had difficulty weighing it correctly, using a small scale I came up with 7 ounces ?
I was told that this could be a mill ball, with that thinking I know there was a large foundry located in Milwaukee 35 miles away from where this was found and 18 miles away from lake Michigan, I would think they would have hauled iron by boat then to the Milwaukee Harbor, on the other hand I do not know of many military skirmishes that could have occurred in southeast Wisconsin , there were a few battles in the area mostly 15 to 50 miles away,

any help would by appreciated

All of that having been said... many people think they are fuzes, because a book which was written back in the late 1960s incorrectly shows them as being CS Girardey Fuze Adapters. Though that book has been reprinted many times, the error has never been corrected. That book is McKee-&-Mason's "bullet book", titled Civil War Projectiles II - Small Arms & Field Artillery.
