10 Weight / Lead Line / Net Sinker

These are called a "Ten Weight" net weight because 10 of them will make up one pound  (+/-).  If you use pure lead and get perfect pours it will be a little over a pound, but pretty close.  If you use unknown lead alloys or get less than perfect pours it a count of ten may come in a little under one pound.  

Nominal size is:

• 3/8 inch (0.375) in diameter. 
• 3 inches in length.
• 3/16 inch (.1875) pass through hole.  (pins included)
• 4 cavities in a mold.
• 10 castings per pound.
