hammer to nipple alignment

[skierman0]

I have this lyman gpp and I think the hammer is not resting well on the top of the nipple (the heel of the cup rests on the rear of the nipple leaving the toe slightly above). It seems to touch off the caps well enough, but it seems that this may lead to abnormal mushrooming of the nipples as well as not completely covering over the hole in the nipple. Obviously this was assembled poorly at some point.
Has anyone else seen this, how big a problem is this, and can anyone think of a way to repair /moderfy (yes, MODERFY; a highly technical term from my brother) this aberration? :idunno:

A simple, quick, easy way to do it is to use a small flat ended cylinder shaped (can't spell cylinderical) grinding stone in a Dremmel tool on the flat in the cupped tip of the hammer.
