Wait, he ran out and left his GF abandoning her?
All I can picture is Peter on The Family Guy, or Homer from The Simpsons seeing a person just laid out on the floor, out like a light, and then he runs out.
Seriously though, people who do this kind of crap make me angry.
I took a female frind shooting one day. She is 5'7" and about 115 lbs. She enjoyed my Ruger SP101, but really liked the trigger on my S&W 460V. So what I like to do for the first 2 or 3 cylinders is load two standard preasure 45 Colts, one 45 Colt +p, then a 454 Casull, and then top it off with a 460 mag. It illustrates the progression of the cartridge development. Then I clean her out with a bore snake quick and start loading full cylinders of 460 mag, then full cylinders of 454, ...... Don't want a pressure build up due to carbon rings.
Anyway, I first had her watch me shoot it. Boom, Boom, BAM, Ka-Boom, and finally "Really..... come on". I had her stand at about 70 degrees to the side, so she felt the cuncussion. I wanted her to be fully aware of what she was about to do. And I made sure she was using proper technique and form.
She fired the Colts off without a problem. Then I waved my arms and said, "Here comes a big one! Hold on!" She indicated she knew what was coming. When she pulled the trigger and the gun fired, she looked at me with her eyes like saucers, and said "I don't want to do a bigger one!" And my response was "Then you shouldn't." and I took the gun back. I fired the 460 round and all was well.
Women can handle large bore magnum revolvers just fine, WITH PROPER INSTRUCTION. However, NO ONE should ever be pushed to shoot any gun or cartridge they are uncomfortable with..... for any reason. Kudos to the OP for helping her out.
I have no tolerance for men who put anyone in harm's way for their own amusement. And if he was truly that ignorant, I hope he has learned his lesson.
And I hope the guy who rented it to them learned too. You don't just hand a gun like that to anyone, no questions asked. You need to at least ask if they have ever shot the caliber before. You also need to make sure they are aware of the gases that will come barreling out of the barrel cylinder gap.
No excuse for putting this girl in harms way.
