Damn, I forgot who's daughter that is as well. She was posted on the forums a few years back.
EDIT: Found her father. That video was from October 2012.
Scroll down a bit.
quoting her father from 2013
" I am Katelyn's dad and she has been shooting since she was 5.
She just started 3Gun last year. Go to fb and give her a 'like' http://www.facebook.com/#!/3gunkatie
Any sexist comments, I'm going to send her your way to take care of my light work!!!! "
