I?m going to try Mech8?s rounds in this ?new? chamber today. If his fit, then I guess I have no choice but to switch to Rem brass and be done with it. If not, then I?ll send it back again and be up to $50 in return shipping at that point and write off using the barrel for this season.

This is not what I expected from SSK. It shouldn?t be hard to open the neck or throat or whatever until the rounds I sent fit, as they do in other SSK chambers. Maybe their focus on AR rounds has put Contender gunsmithing on the back burner? Who knows.
