Check out all the other ballistic calculators there.  Lots of information available on that site.

Except for the RB calculator, all the other tools just get:

Write this down and you no longer need a computer, just a calculator.

Weight of Lead Sphere in grains.
Multiply the cube of the diameter in thousandths of an inch by 1502.6.

Example:  .72 x .72 x .72 = .373428  X 1502.6= 560.8424448

That only works if you have pure lead.  The beauty of the posted calculator is you can weigh your balls and then look up the various materials and get some idea what you are casting.  Or how much impurity you have in your lead.  Sometimes what you think is pure lead turns out to not be. :shake

I find myself in the same body of water as Blue lake ...;

I got the same thing until I clicked on Ballistician's Corner in the blue box on the left. Lot of good calculators there, thanks TS.
Guess the drop down doesn't work right

You are correct, Michael.  On the other hand the formula works well enough in sizes up to 1" even in lead alloys such as flashing, plumbing vents, plumbers lead,  wheelweight metal  and salvaged fishing weights that the error is so slight as to be of no concern.

I think that  in this case perfect is the enemy of good enough.

Imagine a world where the face book trolls could join a forum where the answer is before them. It'd be like so cool for them to look up round ball weights in determining if the lead they got a good deal on is hard or soft.

 :Doh!
