I purchased thousands of LC 30/06 MATCH pull down cases from Pat's reloading in Ohio. Every case had a flash hole that was off center. If reloaders were familiar with case artifacts they would have noticed a seller on EBay was selling 8mm57 cases formed from 30/06 blanks. That was 12+ years ago. I purchases two belts of blank cases that were loaded from once fired cases in Yonkers, NY. Each case was marked.
