Narrative:

I was shown by the FBO owner/manager the proper way to close and lock the nose baggage door prior to beginning flight from microphone. No problem on flight to lou (I closed and locked). When loading at lou, latch and lock seemed to operate normally. Handle and lock both horizontal and solid. On climbing out of 4500 ft MSL for 6500 ft MSL, door opened and momentarily remained up. I pulled the throttles back and slowed aircraft to blue line (10.5). At some point I notified lou departure that my baggage door opened and I would like to land. They (lou) vectored me to monroe county airport and asked if I was experiencing control problems. I replied no. Door slammed approximately 5-6 times then quit. On landing and inspecting door latch was down and lock was in locked position, but approximately 1/8-1/16 inch off horizontal. I am not sure why, because it was fully horizontal on takeoff.
