Mpie427 Posted January 20, 2014 Share Posted January 20, 2014 I just reloaded 700 plus 45's using a Dillon 650...the only brass I had issues with this time was CBC stamped brass. The large Tula primers would not seat. Anyone else have that issue? Link to comment Share on other sites More sharing options...
practical_man Posted January 22, 2014 Share Posted January 22, 2014 Not really. I really like Magtech (CBC) brass. However I only use US primers. Could be tolerance stacking between the primers and brass? Link to comment Share on other sites More sharing options...
TonyK Posted January 22, 2014 Share Posted January 22, 2014 Don't have a lot of it (CBC brass) but I have never had a problem with seating CCI primers. Just for the info according to cartridgecollectors.org, CBC brass is made in Brazil Link to comment Share on other sites More sharing options...
jester121 Posted January 22, 2014 Share Posted January 22, 2014 I separate out the CBC and a couple other head stamps that won't take a Fed primer. Pain in the.... Link to comment Share on other sites More sharing options...
jabbermurph Posted January 22, 2014 Share Posted January 22, 2014 CBCs give me the most trouble in the case gauging department....in 9mm w/.356 Link to comment Share on other sites More sharing options...
Pasley Posted January 22, 2014 Share Posted January 22, 2014 I like CBC/Magtech 9mm brass but it is a little thicker than others. No problems in a roomy Glock chamber or with any U.S. primers. Link to comment Share on other sites More sharing options...
Satch Posted January 22, 2014 Share Posted January 22, 2014 I find CBC headstamp 9mm brass to be problematic when crimping cast lead bullets. The brass taper crimp is not tight enough around an SNS coated bullet. This absolutely occurs with CBC brass. Sometimes I can recrimp it but most always the bullet sets back or is loose. I am culling out and trashing all CBC brass. Link to comment Share on other sites More sharing options...

I haven't had any issues with 45 ACP CBC brass, using Federal and Winchester primers. Link to comment Share on other sites More sharing options...
Mpie427 Posted February 3, 2014 Author Share Posted February 3, 2014 Thanks for the info. I have a can of CBC brass set aside, guess how many and it's yours Next batch I may try US primers to see if that fixes this problem. Saying that, Tula's work great in my 1911's and modified Glock's. So much cheaper when you are shooting tons of rounds a month. Link to comment Share on other sites More sharing options...
njl Posted February 4, 2014 Share Posted February 4, 2014 I just reloaded 700 plus 45's using a Dillon 650...the only brass I had issues with this time was CBC stamped brass. The large Tula primers would not seat. Anyone else have that issue? Do you mean they were really hard to fully seat, or they just wouldn't go in at all? I mostly use CCI primers, but just loaded around 800 .45acp LP using Federal, and every so often, I'd run into a case that didn't want to let the primer fully seat. I'd carefully but forcefully make them go in. This was mixed brass, primarily Winchester, RP, Federal, Speer, PMC, etc. I think most of the tough ones were actually Winchester. I haven't measured, but I suspect the Federal primers are just a tiny bit larger than CCI LP. Link to comment Share on other sites More sharing options...

I never had this problem before, but then I haven't loaded a ton of .45's. Maybe this is the first time I've encountered the CBC brass. I am using the Dillon 650, mixed brass and Tula LP. At some point I may use other primers and see if they seat in the CBC brass. Link to comment Share on other sites More sharing options...
ttolliver Posted February 12, 2014 Share Posted February 12, 2014 +1 for liking CBC I've found Tula SPP can rotate inside my hand primer tool to be edge on. Never had that issue with CCI that I normally keep on the shelf. I think they have a hint more rounded edge on the bottom that allows them to rotate in the column slightly. But experiencing this makes me wonder if the catch that you're experiencing that causes the mashing might be them somehow a little off square when presented to the primer pocket?
