    For those of you enamored of Clays but can't find any, Alliant Clay Dot is a direct replacement.  Even Hodgdon's Ballisticians admit they did a great job reverse engineering Clays.

     

    Yeah, I can't find any of that either :)

     

    I was able to buy four pounds of Sport Pistol powder, than an eight pounder of the same.

     

    it's great powder, and basically the same as Clays in my gun.

     

    Plus it meters better in my Dillon. Sport pistol is a newer powder, so you might be able to find it.

    Clays is great for low flash and works well with plated 115gr RN. Cycles all of our 9's with low recoil and low flash. But it does seem hard to get. I have a bunch, so the wife and I shoot it quite a bit. 

     

    Yeah, Clays powder is great stuff, but largely unattainable these days.

    Anyone need .38 Short Colt brass let me know.  I think I've got 500 new cases I can let go of.  

     

    Once I had my 929 working with Winchester brass I never looked back.  

     

    Sure I'll take them. I'll be in AZ the end of January shooting the AZ State Revolver Championship.

  5. So three pages on how to get a 929 to run correctly :)

     

    Here's what I did to get my 627 to run correctly.

     

    1. Bought the gun

    2. Had a trigger job by the gray ghost in Phoenix

    3. Bought 1000 Starline .38 Short Colt brass

    4. Bought 1000 Bayou Bullets 160gr RN. bullets 

    5. Pew pew pew pew pew pew pew pew, 'merica

     

    Hey, I just saved you guys three pages of reading, you're welcome.

    OK, I'll add my 2 cents worth.  I just grabbed a handful of my sized 9mm brass and ran some pin gauges in them.  I'm using the U-die.  The ranged from .346" to .348" ID varying by headstamp.

    I think whoever it was that cautioned about the powder funnel expanding the brass is correct.

    I turn my powder funnels on a lathe to make sure they're not affecting the neck tension.

    Just measured my funnel with a micrometer and came up with .343", so you can see it's not expanding my brass.  Now, the brass looks a little bulged when loaded (like the snake that just ate a mouse), but no creep to speak of, since it's really grabbing the bullet.  After a match, I measure the overall length of the rounds that are left in full-moon clips and reseat the ones that are .005" longer than I loaded them.  There aren't many, maybe 3 to 5 per 100 fired.  But definitely none that are anywhere close to disassembling themselves in the gun.

     

    I bought a UniqueTek powder funnel (for my Dillon 750) that completely defeats the idea of a U die.

     

    The UniqueTek powder funnel has an outside diameter of .358. It's completely useless. There was no neck tension at all.

    I'm wondering if the U-die actually does anything more than make resizing more difficult in this particular situation. 0.358 bullets are already oversized for 9mm brass. 

     

    Have you experimented with running everything the same except using a standard sizing die? 

     

     

     

    No, but my understanding is a U die is just .001 undersized.

    yrsracer has the formula. I think a u-die  is essential 

     

    Think of a 929 like a racecar.

     

    Most people can't just hop in a NASCAR Sprint Cup car and drive down to the grocery store.

     

    Same thing with a 929. It's pretty useless out of the box.

     

    Fun fact, what's "racecar" spelled backwards?

    Seems like I have finally reached a point of controlling bullets walking out, .357 bullet, 147gr BB, 1.15 oal, .375 crimp, win brass and good accuracy. I have been on this, and other forums for two years trying to figure this out. 

     

    I not sure what you figured out, that's a standard load for a lot of us.

     

    I'm not sure why you were having issues. Glad you got it handled.

    I've done all that and more, nothing short of gluing the bullets in the cases. I'm down to .375" crimp, soon to be .370", way more crimp than I could imagine.

     

    Are we talking about 9mm? Where do you live?

    Thanks for the info - very helpful

     

     

    I also use a Lee U die for 9mm, and Mr Bullet Feeder powder funnel in my Dillon 750. With .358 coated bullets from either Bayou or Blue I don't get any bullet creep.

    Please elaborate on this

    From TK:

     

    The extractor groove diameter on cartridge cases is the most important part of fitment into a moonclip. There is no SAAMI specifications for the extractor groove and each manufacturer makes them as they want.

    Guys:

     

    This has been the thing that I still don't understand.  People complain about the 929 but is it mechanically different than a 627 or is it the 9mm cartridge?

     

    Guys shooting minor loads out of 627's don't seem to have the same problems.

     

    GG

     

     

     

    9mm is a semi auto cartridge. Factory ammo isn't usually crimped.
