Too bad the 90gr Gold Dots are unobtainable.
Nosler has a 90gr bonded 6.8 bullet that is supposed to be good down to 1600. It is pretty stubby though and doesn't look like it'll feed very well.
Barnes' TTSX might work. It has a minimum expansion velocity of 1700gps.
And Cavity Back Bullets has a 95gr that will supposedly open up at only 1400fps.
