I was a Marine if you recall Rogue so I believe I know a little bit about shooting a rifle; and it is my humble opinion she rushed every shot but the last. It also appears the animal was a bit closer on the last shot.<quoted text>
That was about the only segment I watched. Yes, she missed five times, switched to another rifle and got it one the first round. Some times the sights out of zero and you must re zero your rifle. But she should have done that before leaving camp that morning.
Now, if all you know about guns is from watching TV, you are greatly under educated about the subject. Example, I sniper draw a bead on someone and the camera shows that the sights are centered of the subject. Well, that is only good if you are shooting only 200 yards, after that you must hold over the target. And you have to know how much for the range you are shooting at.
If you are shooting a 50 cal Barret at a target a mile away, you have to hold about 64 feet over the target. And then there is wind drift to consider.
I base this mainly on her dad saying the first shot was high. She should have then took her time and adjusted for the second shot but she rushed each subsequent shot until the last when the guy gave her another rifle and something to rest it on.
They had apparently been out for a few days so the rifles and scopes should have been calibrated.
