I've been processing some .45 ACP brass that I've accumulated. Some of it has been in the shop for years. I've been doing this single stage and semi-inspecting it at the same time. I don't look closely at every one, maybe every 8-10. Today I ran across some cases that seemed "off". I don't know why I took notice of them and there were only 3 and they occurred while I was sizing/decapping several dozen.
In inspecting these 3, the flash holes looked oversize. I hadn't been looking at flash holes so I picked up a couple out of the already sized bucket. As best I can determine the flash holes in the 3 were 1/8" diameter. A number 30(.1285" would not enter) A "normal" flash hole was 5/64". This is as close as I could come with various size drills. I may be a little off since I don't have full sets of fractional, number or letter drills, just what I have needed in the past.
All 3 cases were Winchester(one was W-W). The head stamp was no different than all others of the same head stamp with normal flash holes. I have several .45 Colt cases that have much oversize flash holes but these are head stamped BLANK. I don't remember how I found these but I've had them on a shelf above my loading bench for several years.
I did not throw these back in the bucket but I am worried that there are more. Are these dangerous in less than max loads?
