Okay, it's a cold and snowy day in Iowa so I decided to prep some once fired 45ACP brass that I just purchased. I got it all cleaned and deprimed and started cleaning out the primer pocked on my Trim Mate.
Now I'm an old retired fart and I've reloaded tens of thousands of rounds and I've never seen this before. I came across two cases that had extremely large flash holes in them, at least twice the diameter of the normal flash hole. All other dimensions were standard, primer pocket, etc.
As I mentioned, this was supposed to be once fired ammo so I assume this is some type of factory load. What would the purpose of this abnormally large diameter flash hole be?
