You might be ok at 300 yds, I can make good accurate shots to 178. That's the longest shooting lane I have.
The coyote on the tailgate with the wound center mass was about 80yds standing unsupported in the dark. He came from an unexpected location on my right side and I had to pivot my whole body to get the shot. I aimed at the center of his body because it was offhand and it still hit where I aimed.
