Here's a pic of the duds. I haven't torn them down yet. Good looking out, I didn't try to re-seat primers on loaded ammo, just primed cases.
There's powder in the rounds, they pass the shake test.
I load on a progressive but prime by hand, so I have a couple ziplocks filled with primed brass.
I saw a test
, I'm convinced oil will kill a primer from the open face anyway.
I don't know that's what did this or anything, but I gotta eliminate all the variables before I blame the primers.
