I was depriming and cleaning a mixed batch of around 350 pieces of 45 acp brass. I picked up the first two cases off the top of the pile, they had a very large flash hole, a 1/8 drill bit was a loose fit. Sort of odd, all the rest were normal, they were both Winchester and the only ones like that. The flash hole didn't seem to have been bored out.
Anyone seen anything like this?
