Yes, check the shell plate.... and also check you priming punch assembly, make sure it's in there tight. If you still have problems, give Hornady a call, you may have an out of spec primer punch, or the spot on the frame the back end of the punch works against may be out of spec. I've had no problems with either, but looking at the press (I've got one), those are pretty much the only things I can think of that could be a problem -- that, are possibly an out of spec sub plate (the metal plate that is bolted to the top of the RAM, which in turn is what the shell plate sits on).
You could try a thin (and I mean very thin) bit of shim material on the frame where the primer punch pushes back to seat the primer... if that helps, report that to Hornady too, for a proper fix.
