Im a bit skeptical of this being a canister ball. The size doesn't correlate with any of the typical field artillery.
Thinking out of the box a bit... there were some massive caliber sporting guns out there in the latter 18th C. and early 19th C. era... Also there were those known as Wall or Rampart Guns existing that many used very large calibers.. Not the first time that lead balls of this size have been excavated, but are pretty rare.
We have to remember that not everything found in a Civil War era site is Civil War era.. Activities frequently occurred over the same turf over the decades. It was not unusual for us in Virginia to find Rev War... War of 1812... and Civil War artifacts intermingled in the same areas...
I completely agree we have only found 3 of them so far I know this erea was not settled till 1830s and the nearest town was not developed till mid 1850s. I really dont know alot of the pre civil war history of this erea I do know there was a cabin near this site early 1840s. So bullet or cannister or some sort of case shot may remain a mystery.
Ok....sorry to derail the thread, but I just realized something......I always thought "case shot" and "canister" were the same thing. Maybe because I am female and have never really understood how cannon work - except for the obvious - big exploding things come out when they pull the string.
So I'm far from an artillery expert (or any other kind of expert) If someone could explain the difference between case shot and canister Id be most appreciative.
I probably need the "dumbed down" version of the explanation. Please and thank you in advance for whomever is kind enough to explain the difference to me.
My avatar is a artillery shell (cut in half) to reveal the "case-shot" inside. They were lead balls like musket balls (generally). Case-shot was in an artillery shell.
Canister was not in a cannonball. Canister is in a tin can, like a coffee can, filled with large iron balls (generally). And used like a shotgun.
With it being lead, it would more likly be from spherical case. Canister usually used iron balls. Spherical case used lead so that after it was filled with the balls and sulfer, they could drill a cavity in the center to hold the bursting charge.
I did a little creative work with that photo - sized the image so the one on the left measured .69 with my calipers, then measured the one on the right. The larger ball on the right is 1.09"
