CBC apparently makes ammo for military and police forces in brazil. It's possible that their standards are intended to work in semi-auto military auto chambers like the FAL and similar, hence these problems might not show up in those guns but would in the tighter bolt action chambers. just a speculation on my part but plausible in my mind.
Im aware of SAAMI standards but who knows.
