Tang,
I'm proud of you for picking up on a truly salient point: Small, very fast bullets, smacking solid shoulder bones, makes for less-than-ideal terminal performance. Long tracking jobs and extensive meat damage will result. Your choices are to go with a heavier, well-constructed bullet, like the 140AB, or be very careful to place your shot behind the shoulder! If you compare the long-range ballistics of various bullets, you will find that the .264WM doesn't lose much trajectory when shooting the heavier 140gr bullets, but the increase in SD will be much appreciated, should your POI be a few inches forward of where you intended.
Whether you go with 130's or 140's, you're .013" smaller and maybe a couple hundred feet-per-second faster than a .270 Win, so you've got almost the perfect deer rifle!
