Was looking for some dead soft lead, and bought some 1/8” thick lead sheeting at the scrap yard today. They guys there were great, they had pallets of the stuff and had an employee come and cut off a 14lbs piece of sheet for me. Going to try a piece tomorrow and see if the cast balls weighs in at the number provided in the Lyman manual. Material in got here last year was within 2.2% (225 gr vs 230 gr). If you have a local scrap yard check them out.
