9MM 147 gr, Have anyone ever used 9mm 147 gr for their guns? What type of gun....?

Regarding the 147Gr grouping higher. The slower bullet takes longer to leave the barrel, so the muzzle has had more time to rise before the bullet leaves the barrel. This is why slower bullets sometime group considerably higher than lighter faster bullets, out of handguns.
