Am I the only chump who didn't know this was a bad thing? I mean, outside the two asshats at Gander Mountain in Spring Texas who sold them to me? Happened to read a thread on arfcom about this very thing. I've already posted and vented there so this is just a heads up for my family here-know your vendors! Two employees told me that they would be fine for loading 223 in an AR15-stupid asshats, if I may say so again!
