Ignatz Posted April 6, 2009 Share Posted April 6, 2009 Hi, I load on a Dillon 550 with Dillon dies and when I chamber check my loaded rounds, the CBC brand does not always fall below the barrel hood. Its a mixed bag of once fired brass I got and the Federal, RP, Speer and other brands seem to load OK. Could it be because of the previous gun it was fired in? And must the reloaded cartridge be able to fall below the barrel hood or is even or a little over OK? There are NO-GO ones that are obvious not to shoot, but some seem that they would work with the cycling of the gun. thanks Link to comment Share on other sites More sharing options...

kevin c Posted April 7, 2009 Share Posted April 7, 2009 You're dropping the loaded round into the chamber, right? What should stop the movement into the bbl is the case mouth "headspacing" on the foward edge of the chamber, and that should mean the case is entering all the way and is supported along its entire length. The cartridge rim should be forward of the end of the barrel hood. If the case doesn't drop all the way in, the rear portion of the case just forward of the extractor groove is not fully supported, and may blow out if the partially chambered round fires. The round should drop freely into the chamber and "clink" as the case mouth strikes the chamber edge, and the round should turn freely once chambered. If it doesn't do either, you have a problem. I personally had trouble reloading CBC 9mm brass, and no longer use it. Link to comment Share on other sites More sharing options...
h2osport Posted April 7, 2009 Share Posted April 7, 2009 Are you chamber checking in the barrell or in a chamber gauge? Glocks tend to run loose in the chamber, and will typically feed just about anything. That being said, I remove all CBC 9mm from my brass as it consistently will not chamber gauge in a dillon gauge. CBC is probably about 99% of what I have had problems with in the gauge. Can not say that I had any prolems running the CBC through the gun before I started seperating it.

Sean Gaines Posted April 7, 2009 Share Posted April 7, 2009 buy a lee undersize die, and that should cure your problems, or buy the lee factory crimp die. it undersized the brass and goes further down the case Link to comment Share on other sites More sharing options...
uscbigdawg Posted April 7, 2009 Share Posted April 7, 2009 Box up the brass and send it to me. My Glock eats everything. Seriously though. Look at your die setup once more and make sure you have the sizing die as low as you can. If that doesn't fix it (hopefully you're using a Dillon gauge), then I'd buy an EGW die. The Lee's apparently work, and they're cheaper, but I'd get an EGW as George supports the sport. Rich Link to comment Share on other sites More sharing options...
ninefan Posted April 7, 2009 Share Posted April 7, 2009 That CBC brass is complete junk, IMHO. It is one headstamp that is the first to go (into the scrap brass bin). Link to comment Share on other sites More sharing options...
D. Manley Posted April 7, 2009 Share Posted April 7, 2009 Hmmm... Guess I'm odd man out. I run 9MM, .40 and .45 CBC (Magtech) brass through my guns with no issues and yes, I case gauge every round. Honestly I can't tell any difference in it from domestic brands, loading it or shooting it. I do size on a U-Die nowadays but even before, had no issues with it.

scottrebello Posted April 7, 2009 Share Posted April 7, 2009 Just took the extra metal of a Dillon die, to get the carbide sizing piece to bottom out on shellholder. No problems with any brass, range pickups or once fired from others. CBC often wont take a primer though. Scott Link to comment Share on other sites More sharing options...
Ignatz Posted April 7, 2009 Author Share Posted April 7, 2009 Thanks, I've had good luck with CBC brass in 45 and 38spl, so its good to hear I'm not the only one to have problems with the 9mm stuff. thanks...and I have no other 9mm pistol to compare how tight the chamber is on my Glock 34. thanks again Link to comment Share on other sites More sharing options...
Duane Thomas Posted April 7, 2009 Share Posted April 7, 2009 My problem with CBC brass has been severely undersized primer pockets. I also toss all CBC in the trash during the "culling out the crap" phase of sorting range pickup brass. Link to comment Share on other sites More sharing options...
al503 Posted April 7, 2009 Share Posted April 7, 2009 (edited) I've had very good luck with CBC also. 3-4 cycles through my open gun and they look just as good as the Win, Rem, and Speer brass thats run in the same batch. Same with .40's although they get used until they're lost. Don't know if it makes a difference but I'm using Dillon sizing die and the Lee FCD.
