I killed a bunch of animals with 160gr Sierra Game Kings, probably a dozen elk, and 2x as many deer. I swithced to Accubonds when they first came out (early 2000s ish), and have had just as good of luck with them. Not sure if performance is any better or worse, and they shoot almost identical, and everything I shoot with them dies. Recovered Accubonds are similar in weight retention as the Sierras.
I haven't played around with any of the newer powders for reloading in a long time in the 7mm, but had great luck with RL22 and IMR4831. It might not be the fastest out there today, but they shoot tinny little holes and stuff dies on the other end. Every. Time.
