2 Small Round Stone Things...Ammunition?

I bought these 2 stone items from an estate sale. I thought they were clay type marbles. BUT thinking now they may not be since there were no other marbles there. These came from the estate of a former editor of The Providence Journal. Lots of history at this sale. I also bought slides of headlines and people, but thats not important. I took close up magnified pictures. The white stone has a small flat spot.

 

The bangbang lads will need a diameter and weight.

 

About 5/8" each. The white one weighs .904 oz on a jewelry scale, the other is .935 oz.

 

I would think they are lead musket balls... but I'm not an expert... I'm just used to seeing them in all the antique shops around town, I live in a Civil War town.

Thanks for the help everyone. I will check out that link.

 

They look like the sort of musket bullets from our Civil War found all over the place.

 

I used your numbers and calculated a density of 0.46 lb/cubic inch for the material. Lead’s actual density is about 0.41 lb/cubic inch, so I think if you had a way to measure the diameter of those two accurately, the average would be a little over your 5/8” estimate, if they are lead. Your numbers are close to what they should be for lead.

 

A common smoothbore musket caliber used during the American Civil War was 69 caliber, referring to the gun bore diameter. The round lead ball was 0.650 inch diameter, probably what you have.

 

Thanks Springfld. Using a soft sewing tape, the white is about 2", the other is about the same.

 

2 inches/3.14 = 0.64 inch

close enough to the nominal 0.65 inches expected for a 69:cal. musket ball

 

Thanks a bunch Springfld!

 

But, I thought you said they were made of stone? Not lead?

 

I thought they were stone. For the size of these they are a little too heavy to be stone.

 

If only I had seen this yesterday, it would have been Pi Day. (I know it was posted 10 days earlier.

 

lead should leave a mark when rubbed on paper .
