Headstamp Question
I have some 380 Auto brass with a CBC headstamp and don't remember who the manufacturer was. I was loading last night and crinkled a couple of them so I pulled them aside and double checked my notes from last session and sure enough I had the same problem then. They seemed out of spec even after running them through a full length sizer and the bullets seemed tight. I managed to get about 4 out of 100 loaded before I separated the brass. When I shot them last time, the brass came out with scrapes on it from the ejector or a different part of my pistol.
Any help would be appreciated so I don't buy that brand again. |

CBC = Companhia Brasileira de Cartuchos
Packaged and sold here as Magtech. Strange, the occasional 9mm or .45 I pick up reloads ok. |

When you get a loaded round, what do you measure as the OD over the bullet?

Very Interesting
I have loaded Magtech before and not noticed that it had a CBC headstamp and never had problems with it in 9mm.
I just measured all of the ones I loaded and every CBC headstamp has an OD at the case mouth of .375 while all the other brass is .373. Very interesting indeed. |

My guess is that CBC makes Magtech's brass for it with the Magtech headstamp.
