Have shot several whitetail and mule deer with 150BTs in 300WSM doing 3250fps. Most were DRT, the bullet tends to fragment quite a bit so not the best for meat conservation or shoulder shots. I certainly wouldn't use them on elk.
I was only able to push 155 Scenar's to 3075 with H4350 last weekend, I was getting flattened primers and some bolt lift resistance.
