I'm not an expert, but the center of buoyancy for a cone appears to be much further forward than it should be.
That is a limitation of the game due to how buoyancy and nosecones work. You can achieve a more realistic result if you make the nosecone out of multiple segments, but it will have a larger impact in performance.
