Unclenick,
You are right, for some reason I read "fail to extract" which I thought meant stuck brass.
I think that the OP should switch from the CCI 400s to something meant for the AR, but I don't think that the primer is the source of the problem, it might simply be a carbine length gas system was used in his rifle instead of a "middy" and he needs a tad faster powder. Don't know for sure though.
