    It could be weak loads that are not getting the slide quite all the way back, but the load data you shared does not sound like it. Not sure if you really meant 4 cc, or actually meant .4 cc. It would seem that .4 would be about right, but 4 honestly would not fit in a 9mm case. I would double check your load parameters carefully, as it might be border line on the weak side and thus, with this particular bullet, not able to fully function the gun. This could easily leave a scrape or line on the side of the round as the slide runs over it without being quite far enough back to pick it up, yet enough to eject. I did a quick look converting cc to grains with what data you provided and, like I said, if it is .4cc it sounds reasonable...maybe even high for the bullet weight you indicated in the OP. Double check your load data. I am guessing you have been doing this long enough to know how to lube your lead bullets without contaminating powder, so I ruled that idea out because of your experience level. Wish I could truly help more.

    He is using metric measurements I believe.

    Sorry the 2.8 was cm. I should have stated that.

    Ok i didn't even realize that. Aged warrior.is on to something to. What does your load translate into grains? I was using 3.8grains of W-231 for awhile and it was very unreliable in my glock 17. At 4.2 it functions great. Which model do you have? I know earlier you said you were using bullets that weighed 132gr., are you sure of that weight. Very odd size for a 9mm and if you're using a lee mold i don't think Ive ever seen that one.

    The bullet weight is 124 grains for the mold I bought, I was able to look it up. I’ll look at the grains of powder I used tonight when I am home. Thanks to all for your replies.

    Interesting...for a 124 grain bullet, .4cc should be about 4.3 grains of 231. That should be a respectable load. You may want to pull a bullet and weigh the charge to see what is actually in them.

    If that's what it is then the load is fine. I think 4.4 or 4.5 is max according to the data i use. Like i said i use 4.2 and that will function my Glock 17, S&W shield, bersa thunder, luger and FN Hi Power so it's not a wimpy load by any means.

    Plunk Testing:
    The solution to chambering problems is to determine the cause:


    Take the barrel out of the gun. Drop rounds in until you find one that won't chamber. Take that round and "paint" the bullet and case black with Magic Marker or other marker. Drop round in barrel (or gage) and rotate it back-and-forth a few times.


    Remove and inspect the round:


    1) Scratches in the ink on bullet--COL is too long


    2) Scratches in the ink on edge of the case mouth--insufficient crimp


    3) Scratches in the ink just below the case mouth--too much crimp, you're crushing the case


    4) Scratches in the ink on case at base of bullet--bullet seated crooked due to insufficient case expansion (not case mouth flare) or improper seating stem fit


    5) Scratches in the ink on case just above extractor groove--case bulge not removed during sizing. May need a bulge buster.

    Update... shot it again, and still having the same feeding issues, accompanied by light primer strikes. A small percentage feed with no problem, some I need to nudge the slide closed, some won't feed at all, as previously described. As I said, this is the only caliber I have had this issue with...

    Had to reread the whole thread to get my head into this again. After mulling it all again, I was thinking two aspects. First, when they fail to feed, exactly what does that mean? In your last post it sounded like sometimes it just did not quite get the slide closed the last little bit; has that been the nature of these or are they sometimes not picking up the next round, or maybe getting stuck cocked in there? The light primer strikes are another issue, I would think. Could very well need a clean and lube or your cases might be a bit short. I am guessing short cases are not the issue since you are not new to reloading. Excessive crimp could allow the cartridge too far into the chamber too, but that is more scary for overpressure, though I suppose you could induce a light strike. I guess my brain is not firing on all cylinders right now, because it sounds like two separate problems, but both could be caused by gun needing clean and lube. The striker can get gummed up even when all else is cleaned if it gets a lot of lube in there. But, the feeding issue was with two different guns that work fine within jacketed bullets, so...I don’t know!
