While prepping a new batch of Lapua 6BR brass I picked up at the local gun show, I was really shocked to find such glaring inconsistency with the size of the flash holes. I have a flash hole de-burring tool and generally it slides into he holes fine. On my last batch some of the holes were so large as to be sloppy while others were so small as to require reaming. It was a problem with all 3 boxes.
hmmm.
hmmm.
