This situation is impossible. According to experts here, this could ONLY occur using Lee Precision dies and presses. ONLY Lee has such low standards of quality. Such high-end equipment as RCBS could not turn out anything like what you describe.
Only goes to prove that Lee-bashing is unfounded and quality issues can occur anywhere, even in the beloved RCBS, never-let-you-down, produces-perfect-ammo-everytime equipment.
It was supposed to be ridiculous.Any and all manufacturers can have defective products, I highly doubt anyone anywhere would argue otherwise, it's the frequency that matters, and how they deal with it. RCBS has one of the best customer service and product support/guarantee of any manufacturer, anywhere, of anything. They are still not my first choice for most reloading equipment, but definitely are my fall back.
Your statement about Lee and RCBS is ridiculous.
One thing that has not been mentioned is that the rifle these cases were fired in could be the culprit.
