130-150's will work fine for the 270 win. Only way to know is fire them and go from their. I found either to work fine out of my 270's and would just go with whicheverI felt fit best/accuracy (then make adjustments for trajectory if required). If you have a bullet that prints nice groups -1-2" difference in adjustment really isn't a huge deal, as youmust practice at those distances to know whats required or produced by your rifle. However far to many just look at a ballistics table, shoot @ 100 and then assume beyond that what their bullet is doing.
