      This was copied from Corbin;s website (http://www.corbins.com/corewts.htm) for the ease of member’s here.
      Hopefully this helps

      To solve for Core diameter, weight, and length
      Formula: Length = volume/area

      To solve for Area : Area = Pi * (diameter * diameter)/4
      To Solve for Volume: Volume = Weight/density

      Lead density = .4097 lb/cu-in
      Weight (lbs) = Grains/7000

      Here is some tables as a guide:
      Core Lengths per diameter and weight Assuming pure lead, .4097 lb/cu-in.

      Hmm did not post exactly in tables as I had wished I’ll edit the tables for a cleaner print out so bear with me, once completed I’ll delete this second post leaving the first
