    Hi PL. I do it with heavy bullets at less than 1000fps, or in your situation--less than 300--350 meters per second. No problems if you use fast burn rate powders. Medium burn rate powders at reduced charges give me more gas cutting of the lead in the bore. I get very slight barrel leading at the first 15 mm in front of the chamber after 250 to 300 rounds shot.

    My most accurate load in a G17 is with a 148 grain cast lead bullet.

    I shoot lead in stock Glock 9mm, 40, 357 Sig, and 45 acp with good results, if the speeds are less than 1000 fps.

    Your results may vary and I suggest experimenting with loads to get the best results.

    I have shooy many thousands of lead bullets. You MUST
    keep the barrel clean. The polygon rifling does lead up
    faster than standard rifling. With the leading, it causes
    the chamber pressure to go up.
    As the notes from the 1st reply - slow powder, and lighter loads work great.

    Hope this helps.

    Actually shooting hard cast bullets from a SS barrel on my G23, barrel from EFK (sold to me by a friend here on GT), sure i don´t have aby problems, but this isn´t the question now.

    thanks again

    Shooting lead is ok as long as your BHN # is high enough. 21 or so to be safe.

    ...from the Beartooth site:

    Brinnell Harness Number, or BHN as it is abbreviated, is a relative hardness scale._ The numbers are derived from the load bearing ability of of a sample in terms of Kilograms (Kg) supported by one square millimeter (mm²)._ This scale is mathematically progressive, in that tripling the BHN number, triples the sample hardness._ Conversely, if you cut the BHN number in half, the hardness of the sample is half that of the original.
