Girlfriend's reaction to shooting a 50 Cal BMG

My dad and I took my girlfriend to the "Urban Tactical" local shooting range to have some fun. We did the "UT Experience 2.0" package which includes AR 15, Glock 17, EVO Scorpion, 1911, S&W 38 and Hatsan Optima. For her we added the .50 caliber BMG to get her reaction, since we've already done it. This video is just of the 50 cal part shot on my phone.
