The load traveling supersonic will hit a bit lower than the subsonic load; possibly 3" or so. It has to do with bullet bow shockwave forces.

Loading to 1200 will not be as accurate since the bullet will decelerate into transonic speeds which causes "severe instability."

Do yourself a favor and load both to just under supersonic. That will give you more uniform POIs along with better accuracy. I load my 357 using 158gr bullets to 1040fps even though I could go much faster.
