With larger animals like elk, the far side hide often acts like a backstop. It's tough, has considerable stretch, and will stop some pretty fast moving bullets. I don't know how many times I've found my bullet under the hide but it's been a lot. Once a bullet gets that far, it's done all the damage it can do.
I used a 270 for years then switched to a 300 WSM and killed 8 or 10 elk with it. I can't remember if I ever found the bullet under the hide with the 300 but it was almost the norm with the 270.
