Thanks for all info (Somewhat of an information overload for this newbie). It gives me better insight as to what the different pressures do.

Assuming that the lead on a test from firing a weapon is from lead vapor from heat is bad science. Some very basic research will tell you that primers contain a lead oxide compound. I am skeptical that the pressure/heat duration is anywhere near the levels needed to penetrate the metal to melt it let alone bring it to vapor temperatures.

This test probably found oxides of lead from the lead styphnate of the primers. A hazard well known in reloading. Elemental lead is fairly difficult to absorb. I think if the temperature penetration were adequate to vaporize lead, your barrel would anneal after the first shot. :P

Having said that, lead bullets can be problematic in .40 for a handful of reasons. Many .40's are polygonal rifled, and of those, some have a much less than ideal interchange geometry for the fired projectile which leads up the barrel.
