Kinda looks like just a shotput like for track and field. Been a long time since I used one but they look exactly like this and about that size.

204

u/SeeRight_Mills 2d ago

I have an old shotput that looks pretty similar to this. At least I think it does, but can't confirm. About fifteen years ago I thought it would be funny to put it in a small safe. I guess I was thinking if someone robbed me they could have that treasure to obsess over.

Then one day a friend was messing with it and the shotput rolled against the door and apparently broke the lock tumbler. So now I have the most useless 20 pounds of metal sitting in my garage. Literally just an iron ball permanently locked in a busted safe. Maybe after I die the "what's in the box" prank might come to fruition though.

I know I'm not helping OP at all here I guess I just had to get that off my chest.

I wonder how rare it is of an occurrence that a safe is broken from the inside by its contents?

u/Cultural_Term1848 1d ago

Yeah, this. To be sure it's a shotput, weigh it. Man's weighs 7.26 kg(16 lbs) and a woman's 4 kg (8.8 lbs)

26

u/cwthree 2d ago

If it's a shot put, it should have its weight stamped or molded on it.

12

u/Big-Restaurant-7201 2d ago

I didn’t see any stamps or numbers on it.

14

u/hijo_del_mango 2d ago

If you weigh it, most shotputs are either 8.8 or 16 lb.

11

u/drlasr 2d ago

This definitely looks like an 8.8 lb shootout unless OP has gargantuan hands.

1

u/Ornery-Dragonfruit96 1d ago

8lbs is the weight of Jr high shots. 16's are high school weights.

1

u/drlasr 1d ago

Correct, the 16lbs are still much bigger than this.

u/sgdonovan79 2d ago

Or 12 lbs (US high school boys).

u/BrokeBeatScarred 1d ago

Op says it’s 4 lbs 3 oz

14

u/nadanutcase 1d ago

I know 'most everyone else is saying shot put (and that seems reasonable) but my first thought was that it's an old (have to be VERY old) cannon ball. Since it lacks markings, that adds weight to my first thought.

4

u/throwaway_advice_25 1d ago

The lack of markings had me thinking this, though admittedly that would be far less likely, depending on OP's location of course.

2

u/BrokeBeatScarred 1d ago

This is what I was thinking. Civil war canon ball

2

u/my_mind_is_burning 1d ago

It’s very common for cheaper shots to not have numbers stamped onto them, but if weighed it should either be, a 6lbs (middle school girls), 4kg (8.8lbs), 12lbs or 16lbs. This looks like a 4kg tho

Thanks, this is driving me pedantically crazy.

5

u/Skreamie 2d ago

Are they often not perfectly spherical or smooth?

7

u/givemywings 2d ago

The ones we had in school were fairly smooth but not polished or anything. I believe we had some of lower quality that were just for practice that had the casting line on it and if left out in the yard for some time could degrade like this.

After googling the size/weight of a shotput though I think this is close to the diameter range of a women’s shot, but a shot would be heavier according to google. So I was off the mark.

3

u/Dacker503 2d ago

Much too light and a bit small for a shot put. The standard weight for men’s is 16 pounds and 8 pounds, 13 ounces for women. Also, the diameter of a shot put shot is 3.54 inches.

u/Miami_Mice2087 1d ago

u/eliwright235 Artillery Expert 2d ago

Cannonball collector here- definitely not a cannonball! Based on the size, I’d say you’re absolutely right about it being a mill ball.

27

u/Big-Restaurant-7201 2d ago

Thankyou!!! This helps ease my mind and saves me the embarrassment of calling the police for nothing. I did call the museum before receiving your comment as they have a civil war exhibit. They said they would find someone for me. I haven’t heard back yet. Should I call back and cancel?

19

u/eliwright235 Artillery Expert 2d ago

Yeah, no need to bring it to the museum anymore, but props to you for taking that action!
So often when people do stumble across real Civil War cannonballs, they immediately call the bomb squad to blow it up before contacting museums, universities, archaeologists, etc, and they destroy these priceless artifacts without even considering the historical value :(

24

u/interstellar_duster 2d ago

Do people not realize that cannonballs, while projectiles, are not (broadly speaking) explosive? They were literally just big spherical hunks of irons that were launched with a ton of kinetic energy.

31

u/eliwright235 Artillery Expert 1d ago

Well during the Civil War, almost all cannonballs were explosive. So “cannonball” is a pretty broad term, which often leads to this confusion, but it’s actually made off of three separate types: case shot, shell, and solid shot. What you are describing is solid shot, which was mainly used to punch holes in ships and forts. Most cannonballs during the civil war however, were case shot or shells. Case shot is a hollow iron ball, filled with many small lead balls, and a bit of explosive. The explosive would go off, shattering the ball, and shooting the lead balls everywhere. Shells are thicker hollow iron balls, filled entirely with the explosive. When the explosive went off, the shell would shatter, shooting the iron chunks, shrapnel, everywhere.

So while some cannonballs certainly are just solid iron balls, most were very much explosive.

3

u/fdar_giltch 1d ago

How would the explosive be ignited? Was there a mechanism for that or would the impact be enough? 

Would any powder still be "live" after this long? Or would the concern be that the cannonball could be much more recent than the Civil War?

8

u/eliwright235 Artillery Expert 1d ago

So there were four main types of fuses to ignite cannonballs during the Civil War: paper time fuse, Bormann fuse, percussion fuse, and combination fuse.

Paper time fuses are just a bit of gunpowder rolled up in a bit of paper, and cut to length. For example, half inch would burn for one second, an inch would burn for a second, etc. when the cannonball was shot from the cannon, the fire would ignite the fuse, which would burn for a few seconds before exploding the ball.

Bormann fuses worked similarly, it was a metal tube filled with powder, and instead of cutting it for a certain time, you would punch a hole in the tube, which would determine how long it would burn. This is ignited the same way as a paper time fuse.

A percussion fuse ignites when it hit something hard, like those little firecrackers which pop when you throw them on the ground.

Lastly, a combination fuse combined percussion with one of the first types.

About the powder being live: most of the time the powder degrades over time, or is damaged by water, but some shells do remain very much explosive. You shouldn’t be too afraid of the explosive shells though, the powder is pretty stable, and won’t ignite unless you throw it in a fire. If you ever do find an unexploited civil war cannonball or shell, the best action is to contact a collector like myself, who can get it safely defused and safed.

u/Andreeni 1d ago

Dear Artillery Expert,

Can you give me your take on this cannonball, dug up in a garden in 'Lundy's Lane' in Ontario. The chap who found it also uncovered various uniform buttons and other war artifacts presumably from an 1812 battle. It weighs about 16 or 17 pounds. A fastidious home-decorator thought it was ugly, so painted it silver to pretty it up. Any thoughts on this?

3

u/eliwright235 Artillery Expert 1d ago

Hmm, if the diameter is exactly 5.68, which it looks to be in the pictures, that would be a 24 pounder. The weight doesn’t seem right though, a solid 24 pounder should weigh exactly 24 pounds, and your doesn’t. Are you sure it didn’t have a hole somewhere? A 24 pound shell (hollow) weighs 16.8 pounds, which is right on what you say it weighs.

A quick googling says the British did indeed have 24 pounder cannons at the battle of Lundys Lane, so you might have something real!

3

u/Andreeni 1d ago

thanks for the response eliwright235. I will check with the owner of the cannonball, and have him weigh it again, and examine it for holes.

u/Saelyre 1d ago

Early shell fuzes were originally lit before being rammed down the barrel (very dangerous) with a length of fuze with a known burn time depending on range. But by the 18th century fuzes had been developed that were lit by the flash of the propellant charge in the barrel with precut lengths for different timing. They were then superseded by impact and combined timing/impact fuzes for shrapnel shells.

https://en.wikipedia.org/wiki/Artillery_fuze

-7

u/interstellar_duster 1d ago

I agree with your assessment that some cannonballs were essentially civil war era artillery, but I disagree with your statement that “most” of the projectiles fired by cannons during the American civil war were of the explosive type.

I’m willing to be wrong about this, but I find it hard to believe that the majority of round fired out of a cannon in the 1860s were fused, explosive rounds.

You probably have way more experience with this, however, so I suppose I would have to defer to you.

u/pifermeister 2d ago

How does one become a cannonball collector if I might ask?

3

u/eliwright235 Artillery Expert 2d ago

Well, I just bought one at a Civil War relics trade show, got some books to learn, and then from then on I kinda just picked up a new one whenever I had the funds haha. There were hundreds (maybe even thousands?) of unique designs of cannonballs, artillery shells, bolts, grape, & canisters used in the Civil War, so there is near-endless research one can do to learn about them, making this a great hobby!

u/Blirtt 2d ago

Mill ball, I have one too and had to really dig to find out. Found by some train tracks which checks out since they are used to hold down train tarps.

u/VerifiedVoidGirl 1d ago

What about 6lbers? I watched a buddy dig a 6lb solid Rev War cannon ball in front of me at a confirmed Rev War battlefield. We all dug a bunch of roundballs and iron grape shot there as well.

3lb, 4lb, and 9lb solid canon shot all exist as well.

They used 6lbers in the Civil War as well. And some of the balls had seams on them like this.

Though base my experience with the guys at the mill, all of them still have their balls. Though it's potentially from a different mill.

u/Big-Restaurant-7201 2d ago

I’ve searched google already and it looks like it could be a cannonball or a piece of machinery that crushes rocks. It has a center seam which google says could apply to either object. I looked up what a fuse hole looks like and I’m still unsure because there is a fuse hole size marking on the ball though it’s unclear. Is it sealed? I don’t have any experts in my area to take this to either. 

2

u/Big-Restaurant-7201 2d ago

More info, I live in southwest Idaho. So hopefully a higher chance of it NOT exploding in my face. Though there is a small chance of a careless amateur collector dropping it in a field. I just called the Idaho state museum since I can’t find experts of these things in my area. They said they would try and find someone for me. 

3

u/CaptMeme-o 2d ago

It really looks exactly like media from a ball mill. I'm certain that's what it is. How it got in your yard is another thing, but thousands of those are used inside of a cement ball mill, so they aren't uncommon. I used to work for a cement company and have one or more floating around my house.

There is a cement plant in Inkom and a terminal in Idaho Falls. Perhaps it started its journey there.

u/ranger_phil 1d ago

Not an expert at all but I once found a similar item that we (archaeologist and me) idetified as part of a ball mill. These were small chambers with metal balls inside used by miners to crush small amounts of ore when prospecting in the 19th century. Like yours it had seams and rough elements which wouldn’t matter for a ball mill as opposed to a shot put or a projectile for a weapon. I should probably mention that at the time I worked on a national forest that had a lot of gold rush mining activity between 1850 and into the 20th century.

One day I saw a flat deck semi-trailer which appeared to have a load of potatoes? Only 8" deep and uncovered. I thought that was quite odd and walked over to check it out. When I picked one up, I was surprised to find these were random oddly shaped balls of rusted steel. Turned out these were ore grinding balls which were worn down and were being sent to be recycled, melted down and recast.

I believe it's too small for a shot put. If you live near any mines, this appears to be one of the balls used in ball mills. They're used to grind ore for processing. Basically, put a bunch of these in a big cylinder with broken rock, and rotate. The iron balls break the broken rock ore into smaller particles.
