I have a little less charity. It’s her job to sight her gun before the trip, not her dad’s. With her schedule, I can understand, but it’s her gun, her job. Her dad may use another eye, or have a different perspective. The shooter is responsible, IMHO.
I have not seen the episode yet.
From my understanding she first used her Dad’s rifle. Another FR post made the comment that the dad was using the rifle as a “helper” while walking (not a good idea). He fell, and that may have knocked the scope out of whack.
It would seem that prudence would dictate that if you are hunting, you have your own rifle that you are familiar with. Not sure why Sarah did not have, or was not using, her own rifle.
Although it sounds like given a decent rifle, she got it on the “first” shot. (Which perhaps negates my thought that one should have their own, familiar rifle...)
how do you know that the sights were not knocked out of alignment on the trip over?
It wasn't her rifle. It was her dad's rifle, and he had it to her to take the shot. He may have zero'd the scope before he left, but earlier that day he had it on his shoulder when he took a bad fall. That might have knocked the scope out of alignment. But in any case... the scope was obviously way off.
Then she took Becker's rifle and dropped the animal with one shot to the chest. It dropped instantly.
