Brazilian ammunition was being used for training and qualification. I picked up over 1000 once fired CBC head stamp cases.
I decided to load a 100 to test before I loaded the entire lot.
The first clue was widely variable primer seating force.
The second was sizing in the final Lee factory size die.
None of the Remington control cases touched the Lee die.
Most of the CBC cases were sized, some were heavily sized.
The bullet diameter was varied by the extremely variable wall thickness.
The result on the targets is self-explanatory.
