Try some Re-22, with quality 100 gr. bullets. You should have no problem reaching 3500 fps, and typically with good accuracy. With 120 gr. Nosler Partition, 3100 fps is no problem.
For the responders mentioning 270's, I've run that same powder, Re-22, under 130 gr. bullets at over 3150 fps, with great accuracy, and no pressure problems....in 22" barrels.
