I keep mine on low power for everything under 200 yards. I don’t start cranking it up to 10 or more until he’s 300+

The higher power you go the more you can see the imperfections in your ability to hold still. I like to at least think I’m steady. There’s no need for high powers on anything less than 300, but then again, your preference may vary. If you like it on high power then use high power. I just don’t.
