another way to test would be to use a Winchester primer and then a federal primer, they use different compounds.
aluminum for the federal, and lead for the Winchester.
oscarflytyer, "And fwiw, I think all the dead birds from eating lead is hokey BS, but who knows." I know exactly and precisely. Bottom feeding water birds than ingest oxidized lead shot into their craw will get lead oxide poisoning. Scavengers that ingest lead bullets will pass the lead with their stool, unless your bullets had white lead oxide on them. The science has been there for 40 years.
Birds that are bottom feeders are most susceptible, ones that eat plant life off the bottom. The studies done in the 1960's in MN and Wisconsin had about a 5% mortality rate over heavily hunted ponds with lead shot. They had been hunted for about 80 years, so the shot was heavily oxidized. These studies lead to the banning of lead for waterfowl hunting, just because it didn't sink deep enough into the mud to be safe. The falsity of the condor study is that there a few examples of condor poisoning. And those are checked just back ground lead levels for any scavenger on the rung below the top of the food chain, i.e. hawks and coyotes. So CA says it must be from bullets, not the thousands of pounds of tetraethyl lead that came out of car exhaust pipes from 1927 thru 1972. Lead is relatively safe for humans after puberty as a metal, it is the oxide of the metal that is absorbed through the digestive tract that is problem, i.e. kids chewing on toys with leaded paints.Fair enough Ric. But how many? Is it onesies twosies? Or are there mass deaths due to it? Same question with the Condors. Seems to me, they would pass the lead if the ate it, based on what you said above. Asking because I really do not know.
Dont think the green copper oxides harmful? Most metal oxides are...

Science is only as good as the people using it, and it can be "used" to do things the science doesn't support. I'm not saying eating lead is a great idea, but I'm extremely skeptical of simply depending on "the science" without more information on any agendas in play.
I think we should not limit the villain to just 'oxides'. I think lead compounds is a better description. The formula below is what happens when Tetraethyllead burnsSo CA says it must be from bullets, not the thousands of pounds of tetraethyl lead that came out of car exhaust pipes from 1927 thru 1972.

Lead does not vaporize from the flames on the base of the bullet.
HOWEVER......................
A very significant amount of lead is atomized due to gas cutting, abrasion, etc. in the instance of even the best-fitting bullet.
How do I know this?
From shooting plain, lubricated bullets through suppressors. How significant is the quantity of lead dispersed into the air? Well, in fewer than 500 rounds of .45 ACP, in a carbine, the suppressor gained two ounces. In fewer than 800 rounds of .300 AAC Blackout, the suppressor gained 1.5 ounces. The lead alloy was deposited on the baffles and removed by scraping and chipping.
So I began powder-coating my bullets and many thousands of rounds later, have yet to gain any measurable amount of fouling in either suppressor.
