I checked my Barnes manual and they only list one load for RL25, it was for their 130 gr XLC bullet. I think the power is to slow for the 270. My best load for my rifle is 68grs of IMR 7828 with a 130gr Sierra Spz b-tail bullet. My second best is 67grs of RL22 with the 150gr sierra Spz B-tail, I hope this helps.
