I have got chrono readings with Re17 [without pressure sign] that were so high, I would bet big money it was not possible:
270 130 gr NBT moly 3.34" 57.7 gr Re17, 22" barrel measures 3129, 3228, and 3228 fps.

That rifle with 4895 and that bullet is usually 2875 fps.

But once I calculate the powder charge reduction safety margin I need with Re17 wild temperature coefficient, all gains are lost.
