Only if you start perpetuating old wives tales. [smilie=s:Quote:

I think he and I can agree with each other that if one of us starts the other will be the first to grab a rope.
The old wives tale that you shouldn't use WW is one that I'm kinda fond of, leaves more for me. :mrgreen:Quote:

The boollit on left was bottom poured because you have a dirt speck in it and base is not perfectly square.
You guys sound like a bunch of old wives.
That's not a speck of dirt, both bullets were sized and that's a bit of lube from the die.

My suggestion is for everyone but me to bottom pour when shooting BPCR. I bottom poured cast bullets since 1965 when in the AMU for the army. I never ladle poured until I started long range BPCR shooting in the late 90's. (No the 1990's not 1890's). I don't know of any one of the top competitors that shoot any bullets with antimony in them nor do I know any that don't ladle cast. The only time any one of us has ever had problems with high lead levels is when shooting in an indoor range. None of us have any idea whether it is from lead splatter against the steel back stops or if it is from primer dust but it really only matters that it is from an indoor range. Some of our IDPA friends cast a tremendous amount of bullets compared to my Bullseye, BPCR, and occasional twice a month steel plate shoots and they have never had a problem with lead poisoning because they never shoot indoors. -- Bill --
I read that there is a .00000000000000001% chance that a huge asteroid will hit the earth this year. Technically correct, but not something I'm going to waste time worrying about.
you must have spent an hour polishing those pretty bullets!Quote:

Hey, I've got a 50/50 chance of being correct......:kidding:
While I may not have a BS in chemistry or a phd in "heavy metals" (find me an accredited institution that grants that phd and I'll send you 5 dollars) I did minor in chemistry while in college. It's true I haven't had an account on this forum until recently but I have been lurking awhile and have gained other useful info. The fact that I'm a forum newbie in no way discounts the SCIENTIFIC evidence that I have provided that shows that lead vapor does exist at casting temperatures. The only "evidence" I've seen contrary to that is that "it's an old wives tale" and "some guy who's writing a book about this said so".
Even ignoring all that please find where I said you should panic and never cast again because the evil lead will invade your brain. I was merely pointing out that the statement "Lead does not evaporate at anything even close to casting temps" was incorrect. I even provided proof. Nowhere did I say you should stop all activity because you'll immediately get lead poisoning which you imply that I said. The fact that lead vapors exists is merely ANOTHER REASON why good habits should be used. To say otherwise is incorrect. I don't understand why you guys are so invested in telling people that lead vapors don't exist.
+1, and I take pain killers everyday!Quote:

A difference of about 10^8 in vapor pressure between lead at casting temps and water at room temp. Technically it happens but that doesn't make it relevant.
Technically we are all dying from conception on but we don't buy funeral plots as baby gifts.
.000001 pa, is roughly equal to .00986 micrograms per cubic meter of air... OSHA maximum contaminant limits for 8 hours exposure is 50 micrograms per cubic meter of air.Quote:

So, the evaporation at casting temp is miniscule.. and not really even worth worrying about. I am more concerned with washing my hands then having an exhaust fan directly over my melting pot to remove lead vapor.. (it would be nice to remove the other smoke from fluxing..and stirring the pot with wood sticks... though)
Thanks for the good reason to dig into this...
That's signature line material right there if I've ever seen it!Quote:
