280Ai loads

Worked up a load using Barnes 150gr TTSX and it was only running about 2875fps 60 grains H4831sc. Coal was 3.245. My barrel is 22 inches. Had 5 rounds the size of quarter. With this information, am I reaching the full potential of the .280AI. If not what powder should I be trying instead?
