By any chance, do you remember the name of the Springfield CS rep your gun shop dealt with? Just got off the phone with them with the same issue. Explained to him that I’ve seen multiple first hand accounts like yours of this issue, which included lengthy dialogue between owners and Springfield about the issue. This was after I was told that there’s no recalls on the particular rifle for that issue, nor has he ever heard of it. I find this very hard to believe, like they’re trying to play dumb, considering the sheer volume I’m beginning to notice of people having this exact same problem. The only thing I’ve noticed is mine, after some feed lip polishing and tweaking, empty brass extracts without issue, and brass gouging is greatly minimized.
