A couple of examples: In Colorado, I was hunting elk and could hear one of the beasts bashing the brush on a little hillock up above me. I knew he was there, but could not get a shot. The solution was to sprint up the hillock until I saw him, throw the gun to my shoulder, and shoot, all in one motion. I was gambling that I could get a bead and pull the trigger before he pulled his head up from brush bashing. And that is what I did. He fell over straight backwards, and one of his antler tines snapped off in the dirt. I had my scope set on 2.5X. More power, and I couldn’t have done it.
