That was GREAT! I'm glad she didn't have her tongue between her teeth or she might have bitten it off.
The proper way to shoot a gun like that is to lock your elbows to keep your arms straight. Put your body into it and rock with the recoil, letting the gun swing upwards and OVER your head if necessary.
I have an AMT in .50AE and it IS a handful. It's smaller and lighter than the Desert Eagle. From the expressions everyone who has ever fired it blurted out at the time, I named it the "Jesus Christ! Gun"........
NO ONE wanted to fire a second shot....
Which is just as well, because I suspect they would have pushed the gun DOWN and shot the ground in front of them, anticipating the recoil.
