Craig N Posted June 3, 2014 Share Posted June 3, 2014 Who makes/marks the CBC brass? I loaded up some coated bullets and I toss them into a cardboard box on the shelf under my press. I had some break apart/bullet came out. All of them were CBCs. I figured it could be not enough crimp since I was set up for loading lead (same company by the way) and ran em through again.......same thing. It was just odd to me that they were the only brass that did this. Link to comment Share on other sites More sharing options...

al503 Posted June 3, 2014 Share Posted June 3, 2014 They're good to go in my book. I didn't notice any difference between these and other popular head stamps. Link to comment Share on other sites More sharing options...
Sandbagger123 Posted June 3, 2014 Share Posted June 3, 2014 CBC is magtech. never had a problem with them other than they are like SB in that they are hard to resize the first time. i think whata you are experiencing is called "springing" Link to comment Share on other sites More sharing options...
ski_dog Posted June 3, 2014 Share Posted June 3, 2014 I noticed that they increase the OAL by about .005 compared to other mixed brass. Works fine, but it did affect accuracy. Link to comment Share on other sites More sharing options...
mjohn Posted June 3, 2014 Share Posted June 3, 2014 When I load the CBC head stamp brass on my 650, the loaded rounds will never pass the case gauge check and the plunk test. I no longer will use that brass. Now it is in the scrap bucket. Link to comment Share on other sites More sharing options...
cecil Posted June 4, 2014 Share Posted June 4, 2014 anyone ever come across "ammo load" brass ? look inside of them... I throw them in my scrap bucket.. Link to comment Share on other sites More sharing options...
redial Posted June 4, 2014 Share Posted June 4, 2014 CBC had a big KABOOM problem in .308 brass about ten years ago. I'll use their brass in low-pressure pistol rounds with lead bullets but I don't trust 'em beyond that low standard. Mark Link to comment Share on other sites More sharing options...
Mapzter Posted June 4, 2014 Share Posted June 4, 2014 I've used CBC 9mm brass for years and years, and have never had a problem with them passing the gauge, loading on a 1050 with EGW u-die. The brass seems pretty durable, I usually lose it before it wears out, but I've had a few cracked cases, which probably had been through 10+ load cycles.

Craig N Posted June 4, 2014 Author Share Posted June 4, 2014 This is the 1st time I ever had a problem like this. I'm chucking them, better safe than sorry if they came apart in a mag or something. Link to comment Share on other sites More sharing options...
jcc7x7 Posted June 5, 2014 Share Posted June 5, 2014 Load them with everything else in the 9mm. fortunately have never had a problem good fortune figuring it out Link to comment Share on other sites More sharing options...
fishsticks Posted June 5, 2014 Share Posted June 5, 2014 I load straight range pickup 9mm brass on a 550b. Most of my rejects (don't gauge, or split or deprime) are CBC. When I see them before sitting down at the press I toss them. Link to comment Share on other sites More sharing options...
Cfish Posted June 5, 2014 Share Posted June 5, 2014 I toss all the CBC in the recycle bucket. Not worth the time or effort! Link to comment Share on other sites More sharing options...
Dels Posted June 10, 2014 Share Posted June 10, 2014 I noticed that they increase the OAL by about .005 compared to other mixed brass. Works fine, but it did affect accuracy. Exact same experience with regards to OAL. CBC consistently loads longer. Sent from my HTC One using Tapatalk Link to comment Share on other sites More sharing options...

I no longer will use that brass. Now it is in the scrap bucket. My experience as well (on my SDB). I think the brass is a bit thicker, causing this problem, and maybe accounting for the other comments on this thread. I discard it. Link to comment Share on other sites More sharing options...
kevin c Posted June 10, 2014 Share Posted June 10, 2014 anyone ever come across "ammo load" brass ? look inside of them... I throw them in my scrap bucket.. Yeah; internal belt. Really weird. Seen one other HS with the same (gotta check at home to see what brand). Potential pressure issue if using a recipe that assumes normal case volume, probably OK if you work up a load for it specifically. I sort my brass for stuff like this. When I get a few hundred ot this type of 9mm brass, I'll probably make up a soft practice load, then shoot and leave them. Link to comment Share on other sites More sharing options...
Extremo Posted June 10, 2014 Share Posted June 10, 2014 Basicly all my 9mm reloads are CBC/Magtech. Been using them for years and never a problem. Link to comment Share on other sites More sharing options...
rdinga Posted June 11, 2014 Share Posted June 11, 2014 My experience is this brass is thicker than some other brands. If using mixed brass I can tell the difference when the loaded round goes into the crimp die. I would be happy to have a five gallon of just this brass to load and shoot.

rr4406pak Posted June 11, 2014 Share Posted June 11, 2014 I use CBC brass for practice, no reason to throw it away. Definitely would not use them for "match day" loads. Link to comment Share on other sites More sharing options...

I think the brass is a bit thicker, causing this problem, and maybe accounting for the other comments on this thread. I discard it. This is exactly the issue. The brass gets thick closer to the case mouth than other 9mm brass. If I load longer bullets like147s in it they won't gauge or chamber in my PM-9. Too fat near the base of the bullet. Used to keep it for plinking rounds with 115s now just chuck it. Link to comment Share on other sites More sharing options...
phidelt208 Posted June 13, 2014 Share Posted June 13, 2014 I"m had issues with CBC (which came from Magtech) I make it my mission to get trash every case the ends up in my brass. Every other case my rounds come out great. Link to comment Share on other sites More sharing options...
nelly Posted June 16, 2014 Share Posted June 16, 2014 (edited) Here's a site that gives excellent information on Brass, the Ammo companies that make it, for who(Military,Civilian etc) what countries they're in and the quality of each.

Cartridge would go halfway up the feed ramp and stop dead. Couldn’t even force it in by “bumping” the slide! Had the feed ramp repolished by my gunsmith, and all other ammo I feed it works fine. When I took it back to my gunsmith, he examined MY magtech ammo, compared to some he had in back, and mine apparently wasn’t crimped properly where the bullet meets the case. You could even see it with the naked eye. I’ll stay away from this ammunition in the future. It’s also filthy to clean up, soot all over the gun. Stay away!

FF1063 Posted August 29, 2019 Share Posted August 29, 2019 I didn't get the memo and have been happily reloading my 9mm CBC brass over and over. Running smoothly in my Kimber Target II. I buy Mag Tec ammo to get more. Link to comment Share on other sites More sharing options...
