PPQ and lead

I need to clarify something here, there is a big difference between the hardcast alloy bullets I mentioned earlier and the pure lead bullets that my SASS friends reload to shoot with their cowboy guns. Hardcast alloy bullets are comprised of different alloyed metals and may or may not contain some lead, depending on whose manufactured bullet it is. My SASS fiends (I mean friends, Freudian slip) pour their own round nose bullets from recycled lead wheel weights and sometimes press linotype. I would shoot hardcast bullets out of any gun I own, but save the pure lead stuff for the revolvers.

The big difference is cowboy loads in .45lc, .38spc, ect is they are powder puff loads in the 15k-18k psi range. What people fail to understand is 9mm and .40S&W loads are in the 30-35k range. Those soft pure lead boolits will lead any type barrel at those pressures. Sure you could download to less pressures then you run into cycling issues unless you put in a lighter recoil spring. Even then its still in the mid 20k range. The trick and its not black magic is to match the hardness to the pressure. In my case the boolits I were using were in the 22-24 brn.
 
My starting lead loads in my glock weren't really hot enough to properly cycle, OMO. They dropped the brass right at my feet. Factory blasts them up to around ten feet.
 
Greg,

Have you tried any lead in your PPQ yet?

The PPQ doesn't have polygonal rifling but it does have a stepped chamber that may cause issues with lead because they are usually a larger diameter than jacketed bullets.
