In my days machining blow molds there were lots of parts where I had to make a completely through hole. Sometimes those were up to 4 inches deep and I had to go from both sides!
The trick to machining cores like that is to leave about 0.05" on skin all around AND pick milling direction and start point such that when the last bit is milled through, the core gently pushed away from the cutter instead of jumping out.
