    Was kind of a failure:faint:
    My G23 seems to be one of the lead hater versions:dunno:
    Tried a few powders.
    Tried soft, hard and even coated bullets.
    Tried fast, slow and in between..
    Tried a FCD, regular taper crimp, no crimp, mild crimp and heavier crimp.
    Tried long, short and in between with OAL's.

    No matter what by 100 rounds I had VERY BAD leading at the throat and the last half of the barrel.

    The last 10 of 100 rounds were running about 20-25 fps less than the first 10.

    I never got past 100 rounds.

    Surprisingly with lead accuracy was good to fantastic.

    A Precision 155rnfp with 5 grains of WST@ 1.125 is SCARY accurate running around 925fps for the first 10 rounds.

    Also my G23(2009 vintage) tended to really guppy my brass.

    KKM to the rescue.
    Very short wait time for it.
    It loves the same load that did well in the stock barrel.

    And as a big bonus, brass comes out looking like new.

    Try different diameter bullets or were they all the same? Hardness does not matter as much a fit in the barrel.

    No personal experience, but my reading has all pointed to diameter being crucial in polygonal rifling.

    You could always try paper patching them.

    I use bear creek bullets in all my stock barrels with very very little leading

    Sounds like a challenging experiment.

    I like a good challenge once in awhile but that could have become too frustrating for me, at least you got good accuracy.

    Thanks for the info.

    I tried some precision coated bullets, still bad leading.

    Bullets varied from .401 to .4015.

    Going to play around with some test loads in the KKM barrel today.

    Keep us informed, I'm trying lead in my G23 now as well with mixed results in factory barrel.

    I've been shooting hard cast lead reloads in my factory Gen2 G23 barrel since the mid 90's with no problems, although I only shoot about 200 rounds max each time between cleanings. The inside of my barrel looks like new.

    I also fire a couple rounds of FMJ after a couple mags of lead and as the last couple rounds fired for the day. I know many people say firing copper after lead is bad and could kaboom the barrel, but this works for me and has for 20+ years. I also use AA#5 powder in my reloads :wow: and have for 20+ years also. Supposedly there's some rumor that AA#5 and lead shouldn't be used in .40sw Glocks :dunno:

    I've never seen a load that leads shoot accurately. If your loads are shooting well, maybe it's not lead in your barrel.

    I also don't understand your guppied brass. I never get that and my Glock 40's are older then yours.

    Accuracy usually lasted about 25 rounds but was pretty good till then, I was surprised it was there at all.

    Defiantly lead in the barrel, long built up smears.

    My Sep 1990 G22 actually had a bit tighter chamber, cases fired in the G22 would fit in the G23 but not vice versa:dunno:

    What do you mean by "guppied brass"? Is that like the "smiley" on the side of the case?

    Reason I ask, my G23 circa '93 does not do this to cases. I was at the range the other day and the shooter next to me had a newer Glock and I got some of his cases (PMC) when I picked up my brass and they had a prominent "smiley" on the side of them that doesn't fully come out when resized. I wouldn't feel comfortable reloading these cases, maybe light loads, maybe.

    My theory is older barrels like mine have a less case support so the cases bulge uniformly around the whole case which is less noticeable, while newer barrels have more case support so it bulges more in the feed ramp area...thus the smiley?? I may be wrong, but that's my theory.

    Sorry for kind of changing the subject of the thread!

    Spent brass from Glock barrel .422-.423 at mouth and .433(some are more) at fattest point.
    KKM barrel .422 at mouth and .427 at fattest part.
    Sized in lee die .418 mouth and .426 at fattest part

    I don't see 0.010" as "guppied" brass. It seems like you are putting the cart before the horse, trying to justify buying and aftermarnet barrel by making a mountain out of a molehill. But, that's just my opinion.

    I bought the barrel so I could shoot lead not for the tighter chamber, that was just a bonus.
    The Glock brass wasn't what I'd call horrible but with one side of the case blown out a bit it wasn't pretty either.

    I just finish some shooting, after almost 400 rounds of various lead bullets the KKM barrel was PRISTINE :wow:
    about the same as my 1911 barrel after equal amount of lead.

    I'm happy.

    I'm glad you're happy. It's just that terms like "blown out" when your talking about a case expanding 0.007" is a bit dramatic. I think most would call a case expanding twice the thickness of a human hair "normal".

    I have a Glock barrel that happily shoots lead and another that wont shoot 10 rds with out horrible leading.

    My KKM isn't fussy at all either. It will run forever without leading up. Literally.

    Same caliber on the Glock barrels?

    I'm kinda interested on why.
    Looser or tighter barrel, certain tooling, barrels made on Fri or Mon, regardless I knew there was a chance it wouldn't work.

    Thanks on steering me to the safty prime, it's working great:wavey:

    Both 9mm barrels. G34 Gen 3 and G19 Gen 2. The G34 will not shoot lead. If you run a patch down the barrel you can feel it go tight-looser-tight again. It shoots Jacketed fine.

    Glad you like the Safety prime. Mine works great as well. Just loaded up some rifle yesterday with it.

    My G27 gen 3 and G30 gen 3 would not handle lead reloads at all without some serious leading. Like you already know, KKM to the rescue in both calibers, after a disastrous side trip through Lone Wolf barrels for those two Glocks.

    When shooting the G27 and G30 with the KKM barrels the accuracy might ? be a whisper better than factory barrels but the darn shooters function each and every time, not so with the Lone Wolfs.

    My G17 gen 4 will handle lead reloads and hums along with good accuracy and only very minor leading after around 300-400 rounds.

    Who knows why?
