The shutter release is very touchy on the 750. I thought the same thing when I got mine, every once and a while it would double. I paid attention and realized that the button was re-setting very quickly, and if my finger was still on the button it would release again. In my case it was due to my technique and once I modified my technique the problem is no longer. I like the feel of the action in the shutter release, it is very precise.
I had the same problem, solution and outcome as Tom with my new D5300.
