    Choosing a slower powder was the solution to my leading problems. I shot 600 - 700 rounds this weekend doing load development and no leading issues. Just like SNS Casting states, powder choice is a major factor in shooting cast in lead. Maybe now I can sell off the KKM barrels I bought just to be able to shoot cast in the Glocks.

    IME ... I solved the same problem in my G34 by replacing the Glock barrel with a Storm Lake traditionally rifled barrel. It’s a drop in part, it’s fairly inexpensive and will shoot under two inch groups at 25 yards with a basic lead reload. The Glock barrels are notoriously problematic with lead alloys. YMMV.

    It's great to hear you got a clean shooting load !

    Plus 1 on the copper fouling mention. I use a piece of cloth wrapped around a worn brush with Kroil and JB bore paste. Iíll call it clean after about 60 back and forth strokes. Then With a clean patch and JB bore paste polish (purple color paste) Iíll run it back and forth in the barrel about 60 strokes. After that the bore is pretty good looking.

    This also works for me when I cleaned a sewer pipe bore of a Mosin and SMLE.

    I'm having a feeling of Deja vu right about now. Either that, or it's Ground Hog Day all over again.

    Yes, I already have replacement barrels, KKM, that I mentioned I will no longer need since I'm now successfully shooting lead through the stock barrels. GSSF matches do not allow aftermarket barrels, so stock barrels is where it's at for me.
