I use 200 grain NPs in a 300 win mag for everything just about.
That said my daughter has now killed two elk with a .308 and 150 cup and core federals.
She broke both of this bulls front legs last November. He turned 180 degrees after the first hit. When I went to quarter him I could flop both front legs almost straight up without any cutting. He went about 40-50 yards but it was mostly stumbling/falling down a pretty steep hill. Shot distance around 240 yards.
Not a huge sample size for sure. But it's there.
I've shown this photo a couple times. The first time just to brag and now a couple times to show what some "inferior" guns and loads can do. Ok, I'm bragging now too.
