How do the majority of you function in today's world? Aren't you worried about the mass pollution of our lakes and waterways? Or about electro-magnetic induced illnesses? How about the extreme rape of our land resources by clear cutting operations or the oil industry? Or the heavy metal content of many of our fisheries? or avian flu, swine flu, or mad cow disease leaping over to humans, or the extinction of amphibians in North America. No, you are worried about tumbler dust!!?? How the hell do any of you reload at all...you realize that primers contain lead and just de-priming when you re-size contaminates your home (lead styphnates and lead azides are used predominantly) callously murdering your wives and children? What would happen if you had to cast bullets??!! OH MY WORD, better put the entire neighbourhood in a hazmat tent while you rent a suit from the CDC.
Wake up!! Apply some common sense. What is the "extreme dust hazard" that exists with a tumbler that is killing the world's population?? NOTHING. Hype spread by the un-informed to the unknowing and gullible.
Case in point. 15-17yrs ago I was mad a ware (throguh a magazine article) that there exists critically high levels of lead associated with the reloading process which is dangerous to children, leading to cognitive and other health problems. Primers contained lead. Tumblers cleaned the lead off and the powdered lead contaminated the entire area as it settled on the benches, furniture, and central air system. Bullet casting produced lead vapours which also settled into the bench and then was spread throughout the house by the furnace, slowly killing your family!! My children helped me reload all the time!!! NOOOOOO!
So, concerned, I went to work, talked to the Preventative Medicine Officer, explained my concerns, and borrowed a test kit (bear in mind that I am a trained Radiation Safety Officer so I know how to properly grid and swab test areas) to determine my danger levels. I swabbed my entire bench, tools, tumbler, and floor area. NOTHING CAME BACK BEYOND LIMITS! MOST DIDN'T EVEN COME CLOSE TO TRIGGERING ANY CAUTIONS and many were unreadable. I reloaded there for 10 yrs or more, sweeping my bench off and the floor when it was needed. Occasionally vacuuming with a shop vac.
Don't get caught up in this, many people would have you believe that reloading is completely unsafe in all of its aspects. I don't "de-activate" primers if I miss prime something, I just push it out with the de-capping pin. I won't explode! You can't seat primers with a hammer and pucnh, right? well, what if you have a Lee Loader? Far too much "safety crap" involved in the world today!! I have been a carpenter for 30 years, still got all my fingers, vision, and toes. I have been shooting for almost 40yrs, still got everything intact (well maybe hearing). I have been reloading for 30yrs and nothing has exploded, wrecked a gun, or killed me. Have I made mistakes? Sure. Have I had to stop the entire world to fix it?
