If you want regular pass-throughs, I'd likely lean toward a TTSX, Partition, or Accubond. Having said that, most of your cup/core bullets in the 130-140gr range are probably going to give you pass-throughs most times, unless you are working hard angles. That's where the tougher construction of the premium bullets shines. Like others say, the velocity window of the 6.5CM and the higher sectional density of the 130-140gr stuff is going to yield pretty decent penetration with "regular" bullets.
