I just finished casting 250 or so cast bullets.
They're a few thing you have to remember.
WASH YOUR HANDS!!!!!!!!!!!!!!!!
Do not put your hands in you mouth.
Ventilation!!!!!!!!!!!!!!!!!
Primers are just about as bad a cast bullets.
Handling fired brass is just about as bad as cast bullets.
When I dump my tumbler I do it outside.
When I cast bullets I am set up in front of double doors.
The first thing I do when I shoot, load, anything is wash my hands.
I have had my level checked, it is at the high side of normal but I figure as much as I shoot, load, cast, ect....... I am going to be on the high side of normal.
