So I'm giving the 9mm in a Glock a try. Been twenty years since I loaded any lead in a Glock, don't recall a thing I did before.
My boolit is a Lyman 356634, drops at .358 and 140 grains sized & lubed with LARs 2500. See the pic.
The Glock factory barrel and my Lonewolf after market barrel are both .356 and a tiny bit, measured with a Starrett mic.
I have seated the boolit as deep as you see or it will hit the end of the throat/rifling. At first I sized them at .3572, the actual size my ".357" sizing die gives me. Loaded over five grains of HS-6 gave me some pretty good leading out of both barrels. Leading started just slightly passed the end of the chamber, all the way around the barrel and full length.
So without changing anything else, I found a sizer die that would give me .358, used that. Didn't change the leading at all. The load was up at the top, there was a pretty good impression of the breech face's rectangular firing pin hole in the primers. They are Winchester Small Pistol by the way.
So yesterday I dropped the powder to 4.5 grains. Greatly reduced the leading and the primers were rounded with the barest hint of the breech face in 'em. But they still lead.
Mmm.
Tried three grains of Universal Clays, everything else the same of course. No change, leads both barrels.
What the heck am I doing wrong?
