Human Factors
I was flying the ILS to ZZZ. While turning to intercept the LOC; I inadvertently descended approximately 350 ft. below my assigned altitude. Approach gave me a Low Altitude Alert and I climbed back to proper altitude and completed the approach.
GA-7 Pilot reported altitude deviation during ILS approach that caused an ATC low altitude alert.
