Yep, that's why so many indoor ranges don't want you to use lead bullets anymore. This is the kind of stuff Lawyer's wet dreams are made of.
To be honest with you I'm far less concerned with contamination due to handling ingots and bullets than I am with cleaning up around the machines after casting. It's kind of surprising how much in the way of tiny particles of lead you get on the floor. I currently use a broom and dust pan but I'm thinking that maybe I should use a HEPA filtered vacuum cleaner instead.
On another front, I ran my .240/#4 buck mold yesterday. Boy is that a tricky one to dial in. You have to run hot and fast with it. I sprayed the mold with a dry graphite lube prior to casting (didn't want to do it after the mold was hot because I was afraid that the solvent/carrier liquid or propellant in the spray might ignite). By the end of the day I had it working pretty good. I left the mold in the machine and I am going to try it again with even shorter times (no double tap - takes too much time for this tiny little stuff). still, I don't think I will be able to get it to work as a product as it takes too long to make the stuff. If you just want to make yourself a batch of #4 buck though then I wanted to let everyone know that you can do it with Magma's .240 mold. If you're interested in trying PM me and I'll tell you how I pulled it off.
Going to try the .340/00 buck mold after I do one more run with the .240.
Oh, almost forgot, just ordered the parts to semi-automate my Star. The way I'm going to set this up for now is to hand feed the bullets one at a time (that way I inspect for casting flaws at the same time). I will be dropping them into the sizing die with my left hand and then hitting a momentary switch with my left hand with a limit switch used to return the cylinder to top. I can tap the power supply on one of my PLCs for the 24 v needed to power the air valve solenoids. Forcing myself to hit a button with the hand that I just dropped a bullet with may insure that I don't end up with any round holes in the fingers of my left hand. Originally I was going to use a foot switch but then I started thing about my buddy Tom. Tom is missing his left hand.
Anyhow, I'll post vids and pics of it when it is up and running. Once again, for those of you who aren't casting huge quantities the simple foot lever arrangement I am using on my Star might be a good thing. You get to lube and size your bullets and fight the "Battle of the Bulge" all at the same time.
