I have a similar problem, turns out that 70 cases are too long to chamber in my Lymann chamber checker. After separating out all the problem cases the reloading went fine with the others. I will eventuly take my 9 EZ apart and see if they chamber in the barrel, if not then try to rig up a cutter so I don't have to de-prime the cases, hate having to risk mucking up 70 small pistol primers if I don't have to.
