Looks like your standard OOB round to me. You can see the "mushroomed" end where it didnt seat all the way.

I would say send it back to S&W, but when you get it back take it to the range and bring a pair of needle nose so you can tweak the ejector properly so it runs right for YOUR rifle.

Glad no one was hurt
