Last October my BLL peaked at a 9.
Ouch.
Knowing that Gunshot Residue (GSR) generates an approximate 3 foot sphere of lead primer residue (primers used to be mercury compounds-changed to lead based compounds for "health" reasons) I focused on the GSR I knew I was bringing home with me; fired cases.
I had stored fired cases in uncovered cardboard drums inside the building where I have my reloading room. I moved the drums outside where they were protected from rain, but in the breeze. Fired brass was in 5 gallon pails outside with screw lids from Amazon. Thinking that fired shotgun shells were the biggest culprit (biggest primer-biggest shell) I started to deprime shells outside, then toss into a soapy car wash/wax solution, rinse and dry. Brass cases were deprimed indoors, but I wore an industrial respirator and made sure there was good air movement in the room. Deprimed brass went right into the wet tumbler. Surgical gloves worn handling all fired cases. Hand washing along with lead wipes around my mouth/nose after I was done. The "brass" bag, that collects cases after every stage, was also moved outside to enjoy the breeze.
I continued to take my Centrum Silver in the morning along with two Hawaiian Spirulina tablets at night (good tip from Kid Rich).
All shell loading procedures remained the same, using coated and non-coated bullets and lead shot.
My BLL dropped nearly in half in four months to a 5 ! And this was doing a ton of reloading during the winter months.
It was the fired cases after all.
Stay healthy my friends!
