Drill your holes oversized, then dig out the core around the hole (I have a allen wrench that the short side is cut back and sharpened, that I use with my drill), then fill with epoxy, let cure and then drill the proper hole through the hardened epoxy.
Caulk is for seams and secondary for holes. The epoxy is for preserving the integrity of your core. If you unscrewed something on the boat and found it wasn't backfilled with epoxy, what would you think of the person that put it in?
