Lead round ball weight

[blarby]

No problems find ball weight from say #4 buck to 0000 buck...

But I'm looking for bigger.

Anyone have a reference table handy for say .320-.700 lead round ball weights ?

Thanks !

For black powder? Cannon fodder? What are you loading that needs such a range of size and weight?

Anyone have a reference table handy for say .320-.700 lead round ball weights ?

The weight of the spheres, not the powder charge, etc.

Trying to get some reference so's I don't have to buy say...25 molds to find out !

Cannon fodder?

Nope, I have no intention of shooting cannons at my perfectly cast lead balls.

Just out of curiosity, why does it matter ? Are you the lead ball application police ?

If so, I'm using them to edge my driveway.

Pure lead? It should be pretty straight forward to calculate. Volume of a sphere is 4/3 * pi * r^3. A .320" diameter sphere would be 4/3 * 3.14159 * .160^3 = .017157 cubic inches. Lead is .4096 lb per cubic inch, so the weight of that ball would be .007027 lb or about 49 grains. A quick Excel sheet gives me this:
