No, that doesn't sound right. You should easily get over 3,000 FPS without compressed loads. I know the loading manuals will list some of the higher charges as compressed, but remember, those things are written and edited by the lawyers. Plus, the .270 has been around since 1925 so there are a lot of older rifles out there that probably can't handle the higher pressures that a more modern gun can.
With my load (60.0 gr of H4831sc / 130 Barnes T-TSX / Win Brass / CCI BR-2) I get 3,000 FPS out of a 22" Tikka T-3. My manuals list this as the max load, however, during load development I went to 61.0 gr. and was just seeing pressure signs there.
If I were you, I would run an OCW on the IMR4350, the H4831sc, and Reloader 22. My guess is you will see the best velocity with R22 then IMR4350 then H4831sc. You will get the best temp stability in the reverse order. 3,000 + FPS should be easy for a .270 with a 24" barrel and no pressure signs.
