Could very well be.It was probably purchased at the beginning of the introduction of DDNP priming compound and just didn't get shot until now. Or, it could be one of the new Catalyst Primers.
Hope this helps.

Because of the crimped primers? I have to separate out the NATO brass because of that.I have a bunch of NT’s in 9MM and throw them in the recycle bin. Don’t want to waste time with them since they jam up my Lee Loadmaster.
