I lie the Nosler Accubond for deer in 180 grains in my WSM. I'm sure that others will do fine, I just like the idea of a heavier, bonded bullet to peform and hold together at CLOSE range, as well as longer range. It's probably overkill, but they shoot great out of my rifle, and, as the saying goes, there is no such thing as too dead! Also, when you consider the prices of everything else that goes into hunting, a few more bucks for hedging your bet at the moment of truth seems worth it to me.
