Berry's plated bullets question

I ordered 500 Berry's .312" 71 gr. RN. The label says 1250 fps Max. Velocity. What's up with that? 4.5 gr. of Clay Dot under an 80 gr. RN cast from WW is getting me 1400 fps with good accuracy at 25 yds. and no leading to speak of. Any reason not to run them up to 1600 fps? Searching for 2 or 3 of the best 25 yd loads for 100 yd testing.
