You can certainly use 150s on hogs, but on larger hogs, I would use at least 165s, and, better yet, 180s. Still, even with 150s, 165s, or 180s, I would use PREMIUM bullets on hogs, like - Barnes X, Trophy Bonded, Nosler Partition (not ballistic tip), etc.
Now, on whitetail deer, you really don't need anything more than 165s, and even 150s will work well.
