What range? How are your eyes? What paticular animal? Elk vs deer is pretty big difference. For example, prairie dogs are going to take more power at 500+ then elk. I could kill an deer at 600 with a 10x scope easily. I could barely see a prairie dog with 10x if at all. Not that your asking about ground rats but still, its relevant. I think people need to test scopes rather than ask because its completely opinion.
